Hardened Google Workspace MCP

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

With no annotations provided, the description carries full burden but offers limited behavioral insight. It mentions the tool creates a new spreadsheet and returns information, but doesn't disclose permissions needed, rate limits, whether it's idempotent, or error conditions. The return format is briefly described, but more context on behavior is missing.

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 appropriately sized and front-loaded, starting with the core purpose. The Args and Returns sections are structured clearly, though the initial sentence is somewhat redundant with the tool name. Every sentence adds value, making it efficient overall.

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 tool's moderate complexity (3 parameters, no annotations, but with an output schema), the description is somewhat complete. It covers parameters and return values, but lacks context on authentication, error handling, or sibling tool differentiation. The output schema exists, so detailed return explanation isn't needed, but overall completeness is adequate with gaps.

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 description adds significant meaning beyond the input schema, which has 0% description coverage. It explains that 'user_google_email' is the user's Google email address, 'title' is the spreadsheet title, and 'sheet_names' is an optional list for custom sheet names with a default behavior. This compensates well for the schema's lack of descriptions.

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 tool creates a new Google Spreadsheet, specifying the verb 'creates' and resource 'Google Spreadsheet'. It distinguishes from siblings like 'create_doc' or 'create_presentation' by specifying spreadsheet creation, though it doesn't explicitly contrast with 'create_sheet' which might be similar.

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?

No guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites (like authentication), compare with sibling tools (e.g., 'create_sheet' or 'create_drive_file'), or specify use cases beyond the basic creation action.

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