{
  "connection": {
    "host": "example.com",
    "port": 22,
    "username": "user",
    "password": "password"  // 或使用 privateKey
  },
  "command": "ls -la"
}

开发

# 开发模式
npm run build -- --watch

C2.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'execute command' implies a potentially risky operation, it doesn't mention security implications, permission requirements, error handling, or output characteristics. This leaves significant gaps for a tool that interacts with remote systems.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with zero wasted words. It's appropriately sized and front-loaded with the essential information about what the tool does.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool that executes commands on remote servers (a complex, potentially dangerous operation) with no annotations, no output schema, and 0% schema description coverage, the description is severely incomplete. It lacks crucial information about security, permissions, error handling, and what the tool returns.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 0% description coverage, so the description must compensate but fails to do so. It mentions neither of the two parameters ('command' and 'connection') nor their nested properties, leaving all parameter meaning undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('execute command') and target ('on remote server via SSH'), providing a specific verb+resource combination. However, without sibling tools, it cannot demonstrate differentiation from alternatives, so it doesn't reach the highest score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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, prerequisites, or contextual constraints. It simply states what the tool does without any usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3/5.0
Disambiguation5/5

With only one tool, there is no possibility of ambiguity or overlap between tools. The tool's purpose is clearly distinct as it is the sole operation available.

Naming Consistency5/5

The single tool name follows a clear verb_noun pattern (execute_ssh_command), and with only one tool, consistency is inherently perfect as there are no other names to compare against.

Tool Count2/5

One tool is too few for a server named 'SSH MCP Server', which implies broader SSH functionality. A single command execution tool feels thin and incomplete for managing SSH connections, lacking operations like file transfer, session management, or configuration.

Completeness2/5

The tool surface is severely incomplete for SSH operations. It only covers command execution, missing essential functions such as scp for file transfer, key management, or connection setup, which are core to SSH workflows and expected from the server's name.
