A guide for building high-quality MCP servers in Python (FastMCP) or Node/TypeScript (MCP SDK). Source on GitHub ↗
Where each agent looks for it

|---|---|---|---|
| Claude Code | .claude/skills/ | ~/.claude/skills/ | docs ↗ |
| Codex CLI | .agents/skills/ | ~/.agents/skills/ | docs ↗ |
| Cursor | .cursor/skills/ or .agents/skills/ | ~/.cursor/skills/ or ~/.agents/skills/ | docs ↗ |

Install once, use everywhere (one line)
Copy the skill folder into ~/.agents/skills, which Codex reads and Cursor and Gemini CLI also read, then symlink it into ~/.claude/skills for Claude Code:
git clone --depth 1 https://github.com/anthropics/skills.git /tmp/anthropic-skills \
&& mkdir -p ~/.agents/skills ~/.claude/skills \
&& cp -R /tmp/anthropic-skills/skills/mcp-builder ~/.agents/skills/ \
&& ln -sfn ~/.agents/skills/mcp-builder ~/.claude/skills/mcp-builderThe folder contains: SKILL.md, reference/, scripts/. Skills with scripts/ run code on your machine, so read them first. We don't copy the skill's content here; read it at the source.
Check a SKILL.md before you install it
Runs in your browser; nothing is uploaded. It checks the frontmatter (name, description length) and flags hidden HTML comments, remote URLs, shell commands and referenced scripts so you know what to review.
