Create MCP servers — multi-tool services exposed via Model Context Protocol. Use this skill whenever users mention MCP servers, building servers, server scaffolding, tool registration, or want to package tools for distribution via uvx or npx. Also use when the conversation involves stdio transport, server lifecycle, or grouping multiple related tools into a service. Covers Python (FastMCP) and TypeScript (@modelcontextprotocol/sdk) patterns, packaging, and testing. Activate for: -…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MCP Server Creation Create multi-tool MCP servers in Python or TypeScript that follow the Model Context Protocol specification and Anthropic's tool design best practices. ## What MCP Servers Are An MCP server is a process that exposes one or more tools (and optionally resources and prompts) over the Model Context Protocol. Servers communicate via stdio transport — they read JSON-RPC from stdin and write responses to stdout. MCP servers are how you package and distribute tool capabilities. An LLM client (Claude Code, Claude Desktop, etc.) starts the server process and calls its tools. ## When to Create a Server - You have **2+ related tools** that share configuration, state, or domain - You want to **distribute tools** for others to use (via `uvx` or `npx`) - Tools need **shared resources** (database connections, API clients, auth tokens) - You're building a **domain-specific toolkit** (GitHub, database, monitoring, etc.) ## When NOT to Create a Server - Single utility tool — use a standalone tool file (see `mcp-tool-dev` skill) - Claude Code agent, skill, or command — use their respective creation skills - REST API — MCP is for LLM tool calling, not general HTTP services …

How to install
mdr add andisab/swe-marketplace/mcp-server-dev@sha256:f24267a8988e6f3cThe line at the top of this page pins the label git:20260327.71db556, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
