workflow-generator
This server scans software projects to generate visual workflow diagrams or structured JSON analyses of system architecture, concurrency, and bottlenecks.
generate_workflow: Scans a project directory and produces aWORKFLOW.htmlfile — a dark-mode visual diagram showing components, communication paths, concurrency model, capacity estimates, and bottleneck analysis. Supports specifying output path, project directory, and auto-opening in a browser.analyze_workflow: Scans a project and returns a structured JSON summary (no file written) covering detected framework, worker counts, capacity estimates, components (LLMs, storage, queues, external sources), concurrency primitives (semaphores, rate limits), and a ranked bottleneck analysis.Multi-stack support: Works with Python (FastAPI, Flask, Django), Node.js (Express, Nest.js), Go, and mixed projects, while ignoring vendored/generated directories like
node_modulesorvenv.Wide component detection: API frameworks, gateways (nginx, Caddy, Traefik), LLM providers (OpenAI, Anthropic, etc.), vector stores, databases, queues, async primitives, worker/replica counts, and external integrations (Jira, Slack, Stripe, etc.).
Bottleneck reporting: Estimates throughput ceilings and concurrent I/O capacity, ranking bottlenecks from CRITICAL to LOW with mitigation notes.

workflow-generator
Scan any project and generate WORKFLOW.html — a dark-mode visual system diagram showing every component, how they talk to each other, and where your throughput ceiling actually is.
Works with Python, Node.js, Go, Java, Rust, Ruby, and mixed projects. No external dependencies for the core scanner.
Vendored and generated directories (node_modules, venv, site-packages, dist, …) are never scanned,
and capacity figures are clearly labeled as static-analysis estimates.

What it produces
Every generated page contains:
Section | What you get |
Stat row | Workers · Concurrent I/O ceiling · Semaphore limit · Rate limit · Practical throughput |
Architecture diagram | Layered flow: external sources → gateway → API → queues → AI → storage |
Data flow cards | Write path, read/query path, background jobs — inferred from what's detected |
Concurrency table | Every layer: model · ceiling · limiting factor |
Bottleneck analysis | Ranked CRITICAL → LOW with mitigation notes |
Codebase dependency graph | Force-directed module/import graph — click a node to isolate its neighbors, hover for file details. Import-direction edges are clearly distinguished from real observed traffic (see below) |
Guided tour | Spotlight walkthrough of every section, shown automatically the first time a report is opened; replay anytime with the |
Codebase dependency graph
Every source file (Python, JS/TS, Go, Java, Rust, Ruby) becomes a node; every real import becomes
an edge — resolved with a language-appropriate parser (Python's ast module, regex for JS/TS/Go/
Java/Rust/Ruby), not guessed. Files that match an already-detected component (an LLM call, a
database client, a queue) get an edge to that component too, so you can see exactly which files
talk to Redis, OpenAI, etc. Large repos (350+ files) are automatically aggregated into
directory-level nodes so the graph stays readable; override with --graph-detail files or
--graph-detail dirs.
By default the graph only shows what the code says (import direction, static "this file calls
Redis"), which is honest but not the same as real traffic. Pass --access-log /path/to/access.log
(any combined/common log format) to overlay real observed request counts onto the HTTP-entry
edges — and the generated report includes a ready-to-run k6 load-test script
covering up to 5 detected routes, so the "Practical throughput" number can be checked against a
real measurement instead of only a static-analysis estimate.

| Name | Required | Description | Default |
|---|---|---|---|
| project_dir | No | Absolute path to the project root. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided. The description indicates read-only behavior ('no file written') and lists return fields, but lacks details on permissions, side effects, or other behavioral traits.
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?
One sentence covering the main action and a bulleted list of returns. Front-loaded, efficient, no wasted words.
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 tool with one simple parameter and no output schema, the description is fairly complete: it explains the return value exactly. Could be enhanced by more explicit guidance on sibling tool differentiation.
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% (the only parameter 'project_dir' is described in the schema as 'Absolute path to the project root.'). The 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 verb 'Scan' and resource 'project', specifies output format 'structured JSON', and distinguishes from sibling 'generate_workflow' by noting no file is written.
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 implicitly suggests use for analysis vs. generation via 'no file written' and listing of analysis fields, but does not explicitly contrast with 'generate_workflow' or provide when-to-use/alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
generate_workflowA
Scan a project directory and generate WORKFLOW.html — a visual system workflow showing all components, their communication paths, concurrency model, concurrent request capacity, and bottleneck analysis. Works with Python (FastAPI, Flask, Django), Node.js (Express, Nest.js), Go, and mixed projects. Detects: API frameworks, gateways, LLM providers, vector stores, databases, queues, rate limits, async primitives, and worker counts.
| Name | Required | Description | Default |
|---|---|---|---|
| output_file | No | Output path for WORKFLOW.html. Defaults to <project_dir>/WORKFLOW.html. | |
| project_dir | No | Absolute path to the project root. Defaults to current working directory. | |
| open_browser | No | Open the generated file in the default browser. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses the tool scans directories, reads project files, and produces an HTML file. Could mention nondestructive nature or that it doesn't modify files, but current detail is sufficient.
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?
Description is a single paragraph that efficiently conveys purpose, supported projects, and detection capabilities. Every sentence adds value, though slightly lengthy; could be more structured but not wasteful.
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, description thoroughly explains what the generated HTML contains and lists many detectable components. Provides complete understanding of tool's capabilities and output.
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% and parameters are well-described in schema. Description adds context that output file is a visual workflow, but doesn't enhance meaning beyond schema definitions for the three parameters.
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?
Description clearly states the tool scans a project directory and generates a visual workflow HTML file. Verb 'generate' with specific resource 'WORKFLOW.html' and explicit detection capabilities distinguish it from sibling 'analyze_workflow'.
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?
Description specifies supported project types (Python, Node.js, Go, mixed) and frameworks, giving clear context for when to use. However, lacks explicit 'when not to use' or comparison to alternatives like analyze_workflow.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Tool Schema Changelog
Recent tool additions, removals, and schema changes observed during successful MCP inspections. Dates show when Glama detected each change.
2 tool updates
- First observed
analyze_workflow - First observed
generate_workflow
TDQS
Both tools deal with workflow analysis, but they produce different outputs: analyze_workflow returns JSON, generate_workflow creates an HTML file. The descriptions make the distinction clear, though some conceptual overlap remains.
Both tool names follow a consistent verb_noun pattern with snake_case, making them predictable and easy to understand.
Only two tools for a 'workflow generator' server feels thin. The domain likely requires more operations (e.g., update, delete, validate) to be useful.
The server provides analysis and generation but lacks update, delete, or customization tools. Basic lifecycle coverage is missing, limiting agent workflows.
