File contents

mcp-builder (pointer skill)

Pointer skill — the implementation is not stored here. The name above is the stable local contract; the body lives upstream and is fetched/installed from source so consumers always get the latest version.

Canonical source: https://github.com/anthropics/skills/blob/main/skills/mcp-builder/SKILL.md
Raw SKILL.md: https://raw.githubusercontent.com/anthropics/skills/main/skills/mcp-builder/SKILL.md
What it does: A structured four-phase process for building MCP servers that integrate external APIs/services, in Python (FastMCP) or Node/TypeScript (MCP SDK).

Installing this skill

Claude Code (recommended): /plugin marketplace add anthropics/skills, then /plugin install example-skills@anthropic-agent-skills — this skill ships in the example-skills plugin.
Claude.ai (paid plans): already available, no install.
Claude API: upload/enable via the Skills API.
Cursor / GitHub Copilot: copy skills/mcp-builder/ from anthropics/skills into your skills dir (.cursor/skills/, .github/skills/, or the shared .claude/skills/).

Do not copy the upstream body into this file; that would freeze the version and defeat the pointer.
