mcp-abap-adt: Your Gateway to ABAP Development Tools (ADT)
This project provides a server that allows you to interact with SAP ABAP systems using the Model Context Protocol (MCP). Think of it as a bridge that lets tools like Cline (a VS Code extension) talk to your ABAP system and retrieve information like source code, table structures, and more. It's like having a remote control for your ABAP development environment!
This guide is designed for beginners, so we'll walk through everything step-by-step. We'll cover:
Prerequisites: What you need before you start.
Installation and Setup: Getting everything up and running.
Running the Server: Starting the server in different modes.
Integrating with Cline: Connecting this server to the Cline VS Code extension.
Troubleshooting: Common problems and solutions.
Available Tools: A list of the commands you can use.
1. Prerequisites
Before you begin, you'll need a few things:
An SAP ABAP System: This server connects to an existing ABAP system. You'll need:
The system's URL (e.g.,
https://my-sap-system.com:8000)A valid username and password for that system.
The SAP client number (e.g.,
100).Ensure that your SAP system allows connections via ADT (ABAP Development Tools). This usually involves making sure the necessary services are activated in transaction
SICF. Your basis administrator can help with this. Specifically, you will need the following services to be active:/sap/bc/adt
For the
GetTableContentsTool, you will need the implementation of a custom service/z_mcp_abap_adt/z_tablecontent. You can follow this guide here
Git (or GitHub Desktop): We'll use Git to download the project code. You have two options:
Git: The command-line tool. Download Git. Choose the version for your operating system (Windows, macOS, Linux). Follow the installation instructions.
GitHub Desktop: A graphical user interface for Git. Easier for beginners! Download GitHub Desktop. Follow the installation instructions.
Node.js and npm: Node.js is a JavaScript runtime that lets you run JavaScript code outside of a web browser. npm (Node Package Manager) is included with Node.js and is used to install packages (libraries of code).
Download Node.js. Choose the LTS (Long Term Support) version. This is the most stable version. Follow the installation instructions for your operating system. Make sure to include npm in the installation (it's usually included by default).
Verify Installation: After installing Node.js, open a new terminal (command prompt on Windows, Terminal on macOS/Linux) and type:
node -v npm -vYou should see version numbers for both Node.js and npm. If you see an error, Node.js might not be installed correctly, or it might not be in your system's PATH. (See Troubleshooting below).

2. Installation and Setup
Now, let's get the project code and set it up:
Installing via Smithery
To install MCP ABAP Development Tools Server for Cline automatically via Smithery:
npx -y @smithery/cli install @mario-andreschak/mcp-abap-adt --client clineManual Installation
Clone the Repository:
Using Git (command line):
Open a terminal (command prompt or Terminal).
Navigate to the directory where you want to store the project. For example, to put it on your Desktop:
cd DesktopClone the repository:
git clone https://github.com/mario-andreschak/mcp-abap-adtChange into the project directory:
cd mcp-abap-adt # Or whatever the folder name is
Using GitHub Desktop:
Open GitHub Desktop.
Click "File" -> "Clone Repository...".
In the "URL" tab, paste the repository URL.
Choose a local path (where you want to save the project on your computer).
Click "Clone".
Install Dependencies: This downloads all the necessary libraries the project needs. In the terminal, inside the root directory, run:
npm installThis might take a few minutes.
Build the Project: This compiles the code into an executable format.
npm run buildCreate a
.envfile: This file stores sensitive information like your SAP credentials. It's very important to keep this file secure.In the root directory, create a new file named
.env(no extension).Open the
.envfile in a text editor (like Notepad, VS Code, etc.).Add the following lines, replacing the placeholders with your actual SAP system information: Important: If your password contains a "#" character, make sure to enclose your password in quotes!
SAP_URL=https://your-sap-system.com:8000 # Your SAP system URL SAP_USERNAME=your_username # Your SAP username SAP_PASSWORD=your_password # Your SAP password SAP_CLIENT=100 # Your SAP clientImportant: Never share your
.envfile with anyone, and never commit it to a Git repository!
3. Running the Server
To be fair, you usually dont usually "run" this server on it's own. It is supposed to be integrated into an MCP Client like Cline or Claude Desktop. But you can manually run the server in two main ways:
Standalone Mode: This runs the server directly, and it will output messages to the terminal. The server will start and wait for client connections, so potentially rendering it useless except to see if it starts.
Development/Debug Mode: This runs the server with the MCP Inspector. You can open the URL that it outputs in your browser and start playing around.
3.1 Standalone Mode
To run the server in standalone mode, use the following command in the terminal (from the root directory):
npm run startYou should see messages in the terminal indicating that the server is running. It will listen for connections from MCP clients. The server will keep running until you stop it (usually with Ctrl+C).
3.2 Development/Debug Mode (with Inspector)
This mode is useful for debugging.
Start the server in debug mode:
npm run devThis will start the server and output a message like:
🔍 MCP Inspector is up and running at http://localhost:5173 🚀. This is the URL you'll use to open the MCP inspector in your Browser.
4. Integrating with Cline
Cline is a VS Code extension that uses MCP servers to provide language support. Here's how to connect this ABAP server to Cline:
Install Cline: If you haven't already, install the "Cline" extension in VS Code.
Open Cline Settings:
Open the VS Code settings (File -> Preferences -> Settings, or Ctrl+,).
Search for "Cline MCP Settings".
Click "Edit in settings.json". This will open the
cline_mcp_settings.jsonfile. The full path is usually something like:C:\Users\username\AppData\Roaming\Code\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json(replaceusernamewith your Windows username).
Add the Server Configuration: You'll need to add an entry to the
serversarray in thecline_mcp_settings.jsonfile. Here's an example:{ "mcpServers": { "mcp-abap-adt": { "command": "node", "args": [ "C:/PATH_TO/mcp-abap-adt/dist/index.js" ], "disabled": true, "autoApprove": [] } // ... other server configurations ... } }Test the Connection:
Cline should automatically connect to the server. You will see the Server appear in the "MCP Servers" Panel (in the Cline extension, you'll find different buttons on the top.)
Ask Cline to get the Sourcecode of a program and it should mention the MCP Server and should try to use the corresponding tools
5. Troubleshooting
node -vornpm -vgives an error:Make sure Node.js is installed correctly. Try reinstalling it.
Ensure that the Node.js installation directory is in your system's PATH environment variable. On Windows, you can edit environment variables through the System Properties (search for "environment variables" in the Start Menu).
npm installfails:Make sure you have an internet connection.
Try deleting the
node_modulesfolder and runningnpm installagain.If you're behind a proxy, you might need to configure npm to use the proxy. Search online for "npm proxy settings".
Cline doesn't connect to the server:
Double-check the settings in
cline_mcp_settings.json. It must be the correct, absolute path to theroot-serverdirectory, and use double backslashes on Windows.Make sure the server is running (use
npm run startto check).Restart VS Code.
Alternatively:
Navigate to the root folder of mcp-abap-adt in your Explorer, Shift+Right-Click and select "Open Powershell here". (Or open a Powershell and navigate to the folder using
cd C:/PATH_TO/mcp-abap-adt/Run "npm install"
Run "npm run build"
Run "npx @modelcontextprotocol/inspector node dist/index.js"
Open your browser at the URL it outputs. Click "connect" on the left side.
Click "Tools" on the top, then click "List Tools"
Click GetProgram and enter "SAPMV45A" or any other Report name as Program Name on the right
Test and see what the output is
SAP connection errors:
Verify your SAP credentials in the
.envfile.Ensure that the SAP system is running and accessible from your network.
Make sure that your SAP user has the necessary authorizations to access the ADT services.
Check that the required ADT services are activated in transaction
SICF.If you're using self-signed certificates or there is an issue with your SAP systems http config, make sure to set TLS_REJECT_UNAUTHORIZED as described above!

Available Tools
13 toolsGetClassB
Retrieve ABAP class source code
| Name | Required | Description | Default |
|---|---|---|---|
| class_name | Yes | Name of the ABAP class |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are given, and the description does not disclose any behavioral traits such as required permissions, output format, pagination, or error handling. The minimal description fails to compensate for the lack of annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, comprising a single sentence with no unnecessary words. It is front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and no annotations, the description is insufficient for a tool that retrieves source code. It omits details about return format, access restrictions, and potential limitations. While simple, it lacks complete context for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (only parameter 'class_name' has a description). The description adds no additional meaning beyond the schema. Baseline score of 3 applies as the schema already documents the parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Retrieve ABAP class source code' clearly states the action (retrieve) and resource (ABAP class source code). It effectively distinguishes from sibling tools like GetFunction, GetInclude, etc., which retrieve different object types.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. Sibling tools are listed but no explicit conditions, prerequisites, or exclusions are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
GetFunctionB
Retrieve ABAP Function Module source code
| Name | Required | Description | Default |
|---|---|---|---|
| function_name | Yes | Name of the function module | |
| function_group | Yes | Name of the function group |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It only states the action without disclosing side effects, permissions, error handling, or output format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded with key information, no wasted words. Could be expanded slightly but maintains conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple retrieval tool with two parameters and no output schema, the description minimally indicates the resource but lacks details on what the source code output looks like or any limitations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with basic descriptions for both parameters. The tool description adds no additional meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Retrieve') and the resource ('ABAP Function Module source code'), which distinguishes it from sibling tools targeting other object types like GetClass or GetProgram.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidelines on when to use this tool vs. alternatives, but the resource name and sibling tool names make the context implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
GetFunctionGroupC
Retrieve ABAP Function Group source code
| Name | Required | Description | Default |
|---|---|---|---|
| function_group | Yes | Name of the function module |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description must fully convey behavioral traits. It only states 'Retrieve', implying a read operation, but fails to mention error handling, permissions, or what happens if the function group does not exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and front-loaded, using a single sentence. However, it sacrifices completeness for brevity, missing context that could improve usability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of output schema and annotations, the description is incomplete. It does not specify the format of the source code, limitations, or error handling, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already describes the single parameter as 'Name of the function module' with 100% coverage. The description adds no additional semantic value beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description specifies the verb 'Retrieve' and the resource 'ABAP Function Group source code', clearly indicating the tool's function. It distinguishes from siblings like GetFunction (which retrieves a function module) and GetProgram.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like GetFunction or GetInclude. The description lacks any context for appropriate usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
GetIncludeB
Retrieve ABAP Include Source Code
| Name | Required | Description | Default |
|---|---|---|---|
| include_name | Yes | Name of the ABAP Include |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries full burden. It only states the retrieval action but does not disclose safety, authorization needs, or behavior when include is not found. For a mere retrieval tool, this is minimal transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no redundant words. Every word adds value, achieving maximum conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple retrieval tool with one parameter and no output schema, the description is minimally adequate. It covers the primary purpose but lacks details on return format, error handling, or prerequisites, which could help the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the parameter is adequately described as 'Name of the ABAP Include'. The tool description adds no further meaning beyond the schema, which is acceptable given high coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'Retrieve' and resource 'ABAP Include Source Code', clearly indicating the tool's function. However, it does not differentiate from sibling tools like GetProgram or GetFunction, which also retrieve source code for different ABAP objects.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus siblings such as GetProgram or GetFunction. There is no mention of prerequisites, context, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
GetInterfaceC
Retrieve ABAP interface source code
| Name | Required | Description | Default |
|---|---|---|---|
| interface_name | Yes | Name of the ABAP interface |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must bear full burden. Only states retrieval, but lacks details on side effects, authentication, or output constraints. Insufficient for a read tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise single sentence, no unnecessary words. Lacks structural elements like bullet points, but efficiency earns a high score.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema or annotations; description fails to explain return format, prerequisites, or how it differs from 12 siblings. Incomplete for a tool in this context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single required parameter (interface_name). Description adds no extra meaning beyond the schema, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states verb 'Retrieve' and resource 'ABAP interface source code'. However, does not differentiate from sibling tools like GetClass or GetFunction that also retrieve source code, preventing a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like GetTypeInfo or SearchObject. Description is minimal with no context for selection.

GetStructureC
Retrieve ABAP Structure
| Name | Required | Description | Default |
|---|---|---|---|
| structure_name | Yes | Name of the ABAP Structure |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must bear the full burden of behavioral disclosure. It only says 'Retrieve', which implies a read operation, but does not state what is returned, whether it is safe, or any side effects. The complete lack of behavioral details is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise at four words, but it is under-specified lacking essential context. While concise, it does not earn its place as it fails to provide sufficient information for effective tool selection.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description should at least indicate what kind of data is returned (e.g., structure fields). The current description is too sparse to be complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for the single parameter 'structure_name', which is described as 'Name of the ABAP Structure'. The description adds no additional meaning beyond the schema, so a baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Retrieve ABAP Structure' clearly states the action (retrieve) and the resource (ABAP Structure). It distinguishes from siblings like GetClass or GetTable by specifying the object type 'Structure', though it lacks elaboration on what exactly is retrieved (e.g., metadata, definition).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with parameter descriptions. The description adds no extra semantic value beyond what the schema already provides, meeting the baseline for high coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the function: retrieving contents of an ABAP table. However, it does not distinguish from siblings like 'GetTable' which might fetch metadata, or 'SearchObject' which may involve table lookups.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool over alternatives. There is no mention of prerequisites, limitations, or scenarios where another sibling tool would be more appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
GetTransactionC
Retrieve ABAP transaction details
| Name | Required | Description | Default |
|---|---|---|---|
| transaction_name | Yes | Name of the ABAP transaction |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only says 'retrieve', implying a read-only operation, but does not explain authentication needs, error handling, or what happens if the transaction does not exist. This is insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that front-loads the purpose. It contains no unnecessary words. However, it could be slightly expanded to include key details without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no output schema and simple input, the description should at least hint at the output structure or what 'details' entails. It does not, leaving ambiguity. For a retrieval tool, the absence of return value information is a notable gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with the parameter 'transaction_name' having a description 'Name of the ABAP transaction'. The tool description adds no additional meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Retrieve ABAP transaction details' clearly identifies the action (retrieve) and the resource (ABAP transaction details). It distinguishes from sibling tools like GetProgram or GetTable by specifying 'transaction'. However, 'details' is vague and could be more specific.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives such as GetProgram or GetTable. The context is only implicit through the tool name and sibling list. No explicit when/when-not or alternative suggestions are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
GetTypeInfoC
Retrieve ABAP type information
| Name | Required | Description | Default |
|---|---|---|---|
| type_name | Yes | Name of the ABAP type |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only implies a read operation but offers no details on error handling, performance, or what happens when the type does not exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short (one phrase) and front-loaded. However, it is so brief that it borders on under-specification, missing opportunities to add valuable context in a concise way.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool takes a single required parameter and has no output schema, the description is minimally complete but does not cover return values, error conditions, or tie-breakers among many sibling tools. A more complete description would help an agent select and invoke correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with one parameter ('type_name') described as 'Name of the ABAP type'. The description adds no additional semantic meaning beyond what the schema already provides, so baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Retrieve') and the resource ('ABAP type information'). It is distinct from sibling tools like GetTable or GetStructure which focus on specific data dictionary objects, so the purpose is clear.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as GetStructure, GetTable, etc. The description lacks context for selection among the 12 sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
SearchObjectC
Search for ABAP objects using quick search
| Name | Required | Description | Default |
|---|---|---|---|
| query | Yes | Search query string (use * wildcard for partial match) | |
| maxResults | No | Maximum number of results to return |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description provides minimal behavioral info: only 'quick search'. It does not disclose whether the operation is read-only, requires authentication, or how results are structured, leaving significant ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence, but it could include additional useful context without becoming verbose. It is adequately sized but misses opportunities to enhance clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description is incomplete. An agent lacks information about result format, search behavior (e.g., case sensitivity), and potential limitations, which are critical for a search tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so both parameters are well-documented in the schema. The description adds no extra meaning beyond what is already in the schema fields.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Search for ABAP objects' with a verb and resource, and implicitly distinguishes from sibling tools which are specific getters for individual object types. However, it lacks specificity about the scope of object types covered.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use SearchObject versus sibling tools like GetClass or GetProgram. The agent must infer usage from context, increasing risk of incorrect tool selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

SearchObject
TDQS
Each tool targets a distinct ABAP object type (class, function, table, etc.), with clear boundaries. No two tools overlap in purpose.
All tools follow 'Get<ObjectType>' pattern except 'SearchObject' (uses 'Search' instead of 'Get'), which is a minor deviation. Overall consistent verb-noun structure.
13 tools is a reasonable count for an ABAP retrieval server, covering many common object types. Slightly above typical range but not excessive.
The set provides read-only access to many ABAP artifacts, but lacks write operations (create, update, delete) and some common types like CDS views. Notable gaps exist but core retrieval is covered.
