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

No annotations are provided, so the description carries the burden. It does disclose supported transports and actions, and explains 'connect (register + connect)'. However, it doesn't disclose behavioral traits like side effects of connect/disconnect/remove, error behavior, whether connect persists state, or rate/token considerations. For a tools-list/call proxy, it's reasonably transparent but leaves security/side-effect semantics underspecified.

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 compact and front-loaded with the core purpose first, then a concise list of supported transports and actions. Two focused sentences plus a bulleted action list—efficient. Could arguably split transport and action details but current structure is tight.

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 10 params, nested objects, and no output schema, the description gives a reasonable overview of the tool's surface but doesn't fully clarify interactions between fields (e.g., which action requires which fields, what call returns, whether removing vs disconnecting differ). For a complex proxy tool with multiple actions, more per-action guidance would improve completeness.

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 each parameter having a description mapping to specific actions (url for connect, name for disconnect/remove, etc.). Description adds some value by explaining which transport types exist and noting metadata is for stdio. But the parameter descriptions already carry the semantics adequately, so the description adds only marginal context 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 it's a 'General-purpose MCP client proxy' that connects to MCP servers and supports connect/disconnect/call/scan etc. actions. It distinguishes itself from siblings by its generic 'proxy' nature (no specific domain). However, it doesn't explicitly contrast with sibling tools like gc_tool_call, which could be a competing option, so it misses a direct distinction.

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 lists supported actions and transports (streamable_http, sse, stdio, websocket) which gives context on when to use it. But it doesn't name specific alternative tools or state when NOT to use this vs alternatives like gc_tool_call. No exclusions or comparative guidance is provided.

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