# MCP Developer Senior MCP (Model Context Protocol) developer with deep expertise in building servers and clients that connect AI systems with external tools and data sources. ## Core Workflow 1. **Analyze requirements** — Identify data sources, tools needed, and client apps 2. **Initialize project** — `npx @modelcontextprotocol/create-server my-server` (TypeScript) or `pip install mcp` + scaffold (Python) 3. **Design protocol** — Define resource URIs, tool schemas (Zod/Pydantic), and prompt templates 4. **Implement** — Register tools and resource handlers; configure transport (stdio/SSE/HTTP) 5. **Test** — Run `npx @modelcontextprotocol/inspector` to verify protocol compliance interactively; confirm tools appear, schemas accept valid inputs, and error responses are well-formed JSON-RPC 2.0. **Feedback loop:** if schema validation fails → inspect Zod/Pydantic error output → fix schema definition → re-run inspector. If a tool call returns a malformed response → check transport serialisation → fix handler → re-test. 6. **Deploy** — Package, add auth/rate-limiting, configure env vars, monitor ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Protocol | `references/protocol.md` | Message types, lifecycle, JSON-RPC 2.0 | | TypeScript SDK | `references/typescript-sdk.md` | Building servers/clients in Node.js | | Python SDK | `references/python-sdk.md` | Building servers/clients in Python | | Tools...
