Gemini Audio MCP

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

Discloses persistence and dual read/write modes, but lacks details on validation, side effects, or impact on concurrent operations.

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?

Two sentences, front-loaded with purpose; every clause provides necessary guidance without redundancy.

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?

Adequate for basic invocation but omits return value structure (no output schema exists) and valid parameter ranges.

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?

Partially compensates for 43% schema coverage by grouping parameters into semantic categories (format, sample rate, cleanup), but omits duration and transition 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?

Clear action (view/update) and resource (persistent server settings) with specific examples that distinguish it from audio generation siblings.

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?

Provides explicit guidance for the empty-args viewing case but lacks explicit exclusions or alternatives versus sibling tools.

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