Build an MCP server end to end, tailored to how it will be used. Use when asked to build an MCP, create an MCP server, wrap an API as a tool, make a tool for Claude, expose a service to an agent, build a Claude connector, or turn a service into MCP tools. Asks up front who the server is for (just me, my org, or public) and what it wraps, then walks through analyze, build, deploy, scale, and distribute with steps tailored to that answer. Builds on the example-skills:mcp-builder skill 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
# Build MCP Build a Model Context Protocol (MCP) server the right way, end to end. The defining move of this skill: establish the user's context with `AskUserQuestion` before building anything, then tailor every phase to that context. A personal local server and a public hosted server share almost no steps past "build", so branch early and commit to the branch. ## How this relates to mcp-builder The Anthropic `example-skills:mcp-builder` skill is the gold-standard reference for the *implementation* itself: FastMCP and TypeScript SDK patterns, tool design, input/output schemas, annotations, error handling, and evaluation. Do not duplicate it. This skill is the **scope-and-distribution wrapper around it**: it decides what to build, for whom, where it runs, and how it ships. When you reach the build phase, invoke `example-skills:mcp-builder` for the deep implementation guidance and keep this skill's references thin. ## The five phases 1. **Analyze**: understand the service to wrap and pick the right tool boundaries. 2. **Build**: scaffold and implement the server (delegates to mcp-builder). 3. **Deploy**: get it running and registered for the target runtime. …

How to install
mdr add techwolf-ai/ai-first-toolkit/build-mcp@sha256:e37bcb7db9827263The line at the top of this page pins the label git:20260610.f78d26d, 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.
