Gemini Audio MCP

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

Discloses underlying model (Gemini 2.5 Native Audio) hinting at capabilities, but omits side effects, persistence, rate limits, or resource management details.

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?

Extremely compact three-sentence structure with no redundancy; immediately establishes function and optimal use cases.

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?

Adequately covers purpose and implementation for a straightforward 4-parameter tool, though return value format remains unspecified.

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 is fully self-documenting (100% coverage); description adds no parameter-specific semantics but meets baseline expectations.

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 action (generates speech/narration) and target content (scripts, dialogue), though explicit differentiation from sibling audio generators is implied rather than stated.

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 positive usage guidance ('Best for scripts, character dialogue, and narration') but lacks explicit exclusions or references to alternative tools like generate_music.

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