generate_mcp_server

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states this is a generation tool but doesn't clarify if it's a read-only operation, what permissions are needed, whether it overwrites existing files, or what the output entails (e.g., file creation, code generation). For a tool with zero annotation coverage, this is a significant gap in 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, efficient sentence that front-loads the key action ('generate'). It avoids unnecessary words, though it could be slightly more structured by explicitly mentioning dependencies or outcomes. Every word earns its place, making it appropriately concise.

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 complexity of generating a complete MCP server, the description is incomplete. With no annotations, no output schema, and minimal behavioral details, it fails to provide enough context for an agent to understand the tool's full impact, such as what 'complete implementation' includes or how it interacts with other project setup tools. This is inadequate for a potentially high-stakes generation 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?

The input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description adds context by implying the generation is 'based on all gathered requirements,' which provides semantic meaning beyond the empty schema, though it doesn't detail what those requirements are. Baseline is 4 for zero 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?

The description clearly states the action ('generate') and the target resource ('complete MCP server implementation'), making the purpose understandable. However, it doesn't differentiate this tool from its siblings like 'setup_project_foundation' or 'start_mcp_project', which might have overlapping scopes in the MCP project 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?

The description provides no guidance on when to use this tool versus alternatives. It mentions 'based on all gathered requirements' but doesn't specify what constitutes 'gathered requirements' or how this relates to sibling tools like 'setup_project_foundation' or 'confirm_and_proceed', leaving the agent with no explicit usage context.

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