mcp-developer
Use when building, debugging, or extending MCP servers or clients that connect AI systems with external tools and data sources. Invoke to implement tool handlers, configure resource providers, set up stdio/HTTP/SSE transport layers, validate schemas with Zod or Pydantic, debug protocol compliance issues, or scaffold complete MCP server/client projects using TypeScript or Python SDKs.
Install
With your agent
Install OMGSkills skill "jeffallan/claude-skills:mcp-developer" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/Jeffallan/claude-skills /tmp/claude-skills && ln -s /tmp/claude-skills/skills/mcp-developer ~/.claude/skills/mcp-developerFrom README
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) or pip 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/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.
