MCP Drive lacks visible tool definitions in the provided source. Tool files are referenced (e.g., src/mcp/tools/file-move.ts) but their actual schemas, descriptions, and parameter definitions are not included in the code sample. Without access to the actual tool registration code, parameter schemas, and descriptions, scoring must be conservative. The server exports tool factories but the implementation details are opaque. STDIO-only transport further limits production readiness.

• Provide complete tool definitions with explicit JSON Schema input schemas for all 8 tools. Include type, description, and constraints for every parameter.
• Add 50-200 character descriptions to each tool explaining WHAT it does, WHEN to use it, and any prerequisites. Example: 'Move a file to a specific folder in Google Drive. Requires source file ID and destination folder ID. Returns updated file metadata.'
• Document output schemas for all tools. Specify which fields are returned, their types, and which IDs/references are needed for chaining to other tools.
• Implement error handling with actionable guidance. Return structured errors like '{"error": "File not found", "suggestion": "Try searching for the file name first with files-search"}' instead of raw exceptions.
• Migrate from STDIO to HTTP+SSE or Streamable HTTP transport to enable remote access and hosted client compatibility. STDIO limits deployment to local-only scenarios.
