Server has 6 tools with clear verb-noun naming (list_*, create_*, get_*) and reasonable descriptions (avg ~120 chars). All tools have input schemas with typed parameters and descriptions. However, output schemas are not formally documented, responses are inferred from code. Parameter descriptions lack constraints (enums, ranges, formats). Error handling is minimal: HTTP errors are raised but not caught with recovery guidance. No tool annotations (readOnlyHint, destructiveHint). Missing pagination documentation for list_crm_contacts despite accepting page/size params. Overall: functional but below production baseline.

• Add formal output schema documentation for each tool. Use JSON Schema or docstring format: 'Returns: {id: string, name: string, type: string, status: string, model: string, description: string}'.
• Convert parameter examples to enums. For 'source' in list_crm_contacts and create_crm_contact, declare enum: ['linkedin', 'website', 'referral', 'cold_email'] instead of 'e.g. linkedin, website, referral'.
• Wrap HTTP calls in try-except blocks. Catch httpx.HTTPStatusError and return structured error responses: {'error': 'Agent not found', 'recovery': 'Call list_agents() to find valid agent IDs'}.
• Add tool annotations via FastMCP. Use @mcp.tool(annotations={'readOnlyHint': True}) for list_* and get_* tools; use destructiveHint=True for create_*.
• Document pagination in list_crm_contacts description: 'Returns paginated results (default 20 per page, max 100). Use page parameter to iterate. Returns total count for planning.'.
