Check for additional tools whenever your task might benefit from specialized capabilities - even if existing tools could work as a fallback.
| Name | Required | Description | Default |
|---|---|---|---|
| context | Yes | A description of your goal and what kind of tool would help accomplish it. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It states the action ('Check for additional tools') but does not disclose what the tool returns or any side effects. The behavior is fairly self-explanatory for a discovery tool, but the output format is unspecified.
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 sentence, front-loaded with the action, and contains no unnecessary words. It is appropriately sized for the tool's simplicity.
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 tool with one parameter and no output schema, the description explains when to use it but does not mention the return value or any further details. This leaves a moderate gap in understanding the tool's full behavior.
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 schema fully covers the one parameter 'context' with a clear description (100% coverage), so the tool description adds no additional parameter semantics. Baseline 3 applies per the rules.
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 identifies the action ('Check for additional tools') and specifies the purpose ('whenever your task might benefit from specialized capabilities'). It distinguishes itself from sibling tools that handle API reference queries, like search_api_reference or get_api_reference_content.
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?
It explicitly states when to use the tool ('whenever your task might benefit from specialized capabilities') and even encourages use when existing tools could work ('even if existing tools could work as a fallback'). This provides a clear decision rule for the agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool has a clearly distinct purpose: general docs search, API reference search, API reference listing, API content retrieval, and meta tool discovery. The potential overlap between search_api_reference and list_api_reference_pages is resolved by their differing functions and scoping parameters.
Tool names consistently use imperative verbs with underscore separators (ask, get, list, search). The naming is readable and predictable, though 'ask_redpanda_question' is slightly less conventional than the clear 'api_reference' group.
Five tools is well-scoped for a documentation MCP server, covering search, browsing, and content retrieval without unnecessary duplication or bloat.
The server covers general doc search, API reference search, listing, and content retrieval. A dedicated general-doc page fetcher is absent, but ask_redpanda_question returns content sections directly, so the gap is minor and workable.
