# MCP Reference Servers Skill ## When to Use - When building new MCP servers and needing a reference implementation. - When the user wants robust, community-tested servers for common tools (Filesystem, Google Search, Fetch, etc.). - When debugging MCP connection issues using standardized servers. ## Reference [MCP Reference Servers GitHub](https://github.com/modelcontextprotocol/servers) ## Instructions ### 1. Identify Target Server - Review the `src` directory in the reference repository to see available servers. - Common servers include: - `fetch`: For web page scraping. - `filesystem`: For local file access. - `google-search`: For web searching capabilities. - `postgres`: For database interaction. ### 2. Implementation & Setup - Most reference servers are built with Node.js/TypeScript or Python. - Follow the `README.md` within each sub-directory for build and run instructions. - Ensure the appropriate runtime (Node.js 18+ or Python 3.10+) is installed. ### 3. Usage via MCP Configuration ```json { "mcpServers": { "server-name": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-name"], "env": { "ENV_VAR": "value" } } } } ``` ## Quality Gates - Use `npx` for quick access without local installation unless performance is a concern. - Keep environment variables secure in protected configuration files. - Verify the server's capabilities via `list_tools` command after initialization.
