xiaomingx MCP Builder
Use this skill when the user asks to create, configure, or debug an MCP server or tool integration.
Design Rules
- Prefer stdio MCP servers for local tools and HTTP/SSE for remote services.
- Keep tool schemas small, typed, and explicit. Return structured JSON where possible.
- Put secrets in environment variables, never in committed config.
- For HTTP/SSE clients, send
Accept: application/json, text/event-streamby default unless the server explicitly requires something else. - Add timeouts and clear error messages around external APIs.
DeepSeek Setup
Common commands:
deepseek mcp init
deepseek mcp add my-server --command node --arg server.js
deepseek mcp add remote-server --url http://127.0.0.1:3000/mcp
deepseek mcp list
deepseek mcp validate
deepseek mcp tools
HTTP/SSE entries can include per-server headers in ~/.mimofan/mcp.json when
credentials or custom routing headers are required.
Workflow
- Define the service boundary and the minimum useful tools.
- Choose transport and credential handling.
- Implement the server using a maintained MCP SDK when available.
- Add the server with
mimofan mcp addor edit~/.mimofan/mcp.json. - Run
deepseek mcp validate, thendeepseek mcp tools. - Test one happy path and one failure path before calling it done.
