This MCP server exhibits severe gaps across all definition quality dimensions. The server registers 7 tools, but critical inspection reveals: (1) NO visible input schemas in the provided source code, the Dockerfile and Makefile contain build/deployment configuration but do NOT show tool implementations, parameter validation, or schema definitions; (2) tool descriptions are present but extremely brief (10-40 chars) and lack WHAT/WHEN/output guidance required for LLM planning; (3) parameter descriptions are completely absent, there is no evidence of what parameters these tools accept, their types, constraints, or valid ranges; (4) output schemas are undocumented, it is impossible to determine what fields agents receive after tool invocation; (5) error handling is not visible in the source provided. The Dockerfile shows deployment infrastructure and the Makefile shows build orchestration, but neither reveals the actual tool handler code. Without access to the handler implementations (api/mcp/registry/index.ts is listed as the source file but not provided in full detail), we cannot verify schema compliance.

• Provide complete tool handler code (api/mcp/registry/index.ts) showing full schema definitions, parameter validation, and output structures.
• Expand each tool description to 50-200 chars following this pattern: 'Retrieves [WHAT] from [SOURCE]. Use this when [WHEN]. Returns [OUTPUT STRUCTURE].' Example: 'Retrieves current geopolitical risk scores for a specified country. Use this to assess conflict likelihood before market analysis. Returns risk_score (0-100), primary_threat, confidence_level, last_updated_at.'
• Document every parameter with: type, description (10-100 chars), constraints (min/max, enum, pattern), and whether it accepts friendly names or requires system IDs. Example: 'country_code: ISO 3166-1 alpha-2 code (e.g. US, GB, RU). Alternatively accepts country_name (e.g. United States).'
• Define output schemas explicitly. Specify field names, types (string, number, boolean, array, object), and required fields. Example for get_risk_score: '{"risk_score": number (0-100), "primary_threat": enum (military|economic|cyber|political|maritime), "confidence_level": number (0-1), "last_updated_at": ISO8601 string}'.
• Implement error handling that categorizes failures and provides recovery guidance. Example: 'Country code not found: US. Valid codes: USA, GBR, RUS. Did you mean United States? Call with country_code="USA".'
• Add pagination and result limits to tools returning lists. Include page/offset, limit, and total_count in both parameters and responses. Example: 'list_tools returns max 100 items per page. Pass page=1, limit=20 to paginate.'
