Single utility tool with adequate naming but minimal description quality and missing output schema documentation. The tool `get_config_path` follows verb_noun convention (positive), but the description is generic and lacks context about when/why to use it. Input parameters have basic descriptions but lack validation constraints (enums, ranges). No documented output schema. The server appears to be a utility library without proper MCP tool registration metadata, tool definitions are inferred from the Python function signature rather than explicitly registered with full MCP schemas. This inference capping combined with missing output documentation keeps the score in the D range.

• Convert 'name' parameter to enum constraint with explicit values: ['claude_desktop', 'cline', 'roo_code', 'claude_code', 'vscode', 'cursor', 'mcphub.nvim', 'windsurf', 'mcplinker', 'default']. Document that invalid names default to 'mcp.json' fallback.
• Expand tool description to 100-150 chars explaining purpose and primary use case: e.g., 'Returns the platform-specific configuration file path for MCP client applications (Claude Desktop, VSCode extensions, terminal editors). Use this to locate or validate config file locations before reading or writing MCP server configurations.'
• Add explicit output schema documentation. Specify return type: string (absolute file path), and clarify that empty string '' is returned if the application+platform combination is unsupported (e.g., cline on Windows).
• Enhance 'path' parameter description: 'Optional absolute base path to override the user home directory. If provided, configuration paths will be relative to this directory instead of $HOME. Useful for testing or non-standard installations. Format: absolute filesystem path (string).'
• Document error cases and recovery: 'Returns empty string if application name is not recognized on current platform. Verify application name is in the supported list before calling. Check platform-specific paths exist before attempting to read.'
• Add parameter validation notes: e.g., 'name parameter must be one of the predefined application identifiers. Invalid names do not raise errors; they return a default fallback path (mcp.json).' This prevents silent failures from typos.
