Gemini Audio MCP

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

No annotations provided, but description compensates by disclosing specific model (Lyria-3-clip-preview) and pricing ($0.04/req), adding crucial operational context.

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?

Three tightly constructed sentences: purpose definition, usage guidance, and cost disclosure—each earns its place with no 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 tool complexity but missing return value specification (critical given no output schema exists to indicate what the tool produces).

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?

With 67% schema coverage, description adds no parameter semantics; fails to explain undocumented 'auto_play' parameter or clarify expected prompt structure beyond 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?

Clear specific verbs ('generates isolated, short-duration sound effects and foley') with concrete examples, and implicitly distinguishes from siblings (generate_music, generate_soundscape) via 'one-shot' and 'isolated' qualifiers.

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?

'Best for specific one-shot audio cues' provides clear contextual guidance for when to select this over sibling audio tools, though lacks explicit 'when not to use' exclusions.

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