This MCP server exhibits significant quality gaps across naming, descriptions, parameters, and schema documentation. While tool definitions are visible in the source code (tickets-client.ts), they lack the rigor expected of production-grade agent tools. Naming is inconsistent (getAll vs changeStatus mixing camelCase conventions without verb prefixes in some cases). Descriptions are present but generic and lack context for LLM decision-making. Parameters have type definitions but lack depth in descriptions explaining constraints, dependencies, and valid ranges. Output schemas are undocumented, the LLM cannot see what fields to expect from responses. Error handling is minimal; the code throws raw HTTP errors without actionable recovery guidance. The server exposes database credentials in plaintext within source code, a critical security violation. Most tools are READ_ONLY, which is appropriate for discovery, but WRITE tools (changeStatus, sendMessage) lack confirmation steps or dry-run support, inviting agent mistakes. Overall, this reads like an internal prototype rather than a public-facing tool set.

• Add full output schema documentation for every tool. Use TypeScript interfaces or JSON Schema to document return types. Example: getById should document {id: number, status: string, mensajes: TicketMessage[], createdAt: string, updatedAt: string, ...}. This enables LLMs to chain calls correctly.
• Move all credentials to environment variables. Replace hardcoded COUCHDB_USER and COUCHDB_PASS with process.env.COUCHDB_USER and process.env.COUCHDB_PASS. Document the required env vars in a README or deployment guide.
• Enhance parameter descriptions with constraints. E.g., 'pin' should read: 'User PIN (integer, 1 - 999999). If PIN not found, returns empty list.' Add format, range, and error behavior to all params.
• Add a dry-run flag to WRITE tools (changeStatus, sendMessage). E.g., changeStatus(ticketId, status, {dryRun: true}) returns {would_change: true, old_status: 'pendiente', new_status: 'completado'} without persisting, letting agents preview changes before committing.
• Implement actionable error responses. Wrap raw HTTP errors in recovery hints: 'Conflict (409): Document was modified. Call getById() to fetch the latest state and retry.' This guides the LLM toward resolution.
• Add limit and offset parameters to getAll(). Default to limit=50, offset=0. Return {tickets: TicketSummary[], total: number, hasMore: boolean}. This prevents context explosion and matches pattern:paginated-result.
• Expand tool descriptions to 80 - 150 characters. Explain when to call each tool. E.g., getAll(): 'Fetch all tickets (summary view). Use to discover tickets, filter by status, or bulk operations. Returns up to 50 results; use offset for pagination.' This aids LLM selection.
