mcp-developer
Build and debug MCP servers and clients connecting AI systems with external tools and data sources.
- Supports TypeScript (Node.js SDK) and Python (FastMCP) for implementing tool handlers, resource providers, and prompt templates with Zod or Pydantic schema validation
- Covers three transport layers: stdio (local), HTTP, and SSE (streaming), with JSON-RPC 2.0 protocol compliance and interactive debugging via the MCP inspector
- Includes scaffolding workflows, schema design patterns, and error handling best practices for connecting Claude and other AI systems to APIs, databases, and custom data sources
- Enforces input validation, authentication, rate limiting, and comprehensive error responses to prevent protocol violations and security issues
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
- Analyze requirements — Identify data sources, tools needed, and client apps
- Initialize project —
npx @modelcontextprotocol/create-server my-server(TypeScript) orpip install mcp+ scaffold (Python) - Design protocol — Define resource URIs, tool schemas (Zod/Pydantic), and prompt templates
- Implement — Register tools and resource handlers; configure transport (stdio/SSE/HTTP)
- Test — Run
npx @modelcontextprotocol/inspectorto 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. - Deploy — Package, add auth/rate-limiting, configure env vars, monitor
