MCP builder
Builds a Model Context Protocol server — tool design, transport, schema, the mistakes that make a server unusable.
Installation
$ npx skills add anthropics/skillsThe CLI's unit is the repository, so this installs everything in anthropics/skills, not mcp-builder alone. It writes into whichever agent directories it finds — Claude Code, Codex, Cursor, Copilot, Windsurf, Zed.
Summary
Builds a Model Context Protocol server — tool design, transport, schema, the mistakes that make a server unusable.
- Reach for it when you are exposing an internal system to agents and want the tool surface designed rather than generated.
- Sits in Implement — writing the change: framework-specific conventions, and the discipline that keeps a long agent run on the rails.
- Stack-agnostic — nothing in it assumes a particular language or framework.
- Published by Anthropic, who ship the thing it is about — a stronger claim than a well-regarded engineer having written something good.
- Installing pulls the whole anthropics/skills repository: this catalogue lists 3 other entries from it, and the repo may hold more.

The agent itself
The full text lives with its publisher and changes when they change it. Read it there rather than here — a mirrored copy of somebody else's procedure goes stale silently, and this page would have no way of telling you.
