Ask whether a Claude Code skill actually works — before you install it.
GitHub has tens of thousands of SKILL.md files. Almost none have been run by anyone but their author.
SkillProof installs them from their repo, triggers them, and runs them on a real
task against a no-skill baseline. This MCP server puts those verdicts in your agent's hands.
That is the whole point. A directory that only lists winners tells you nothing.
| Tool | What it answers |
|---|---|
find_skill | "Is there a tested skill for X?" — ranked matches with verdict, score, test notes, install command |
check_skill | "Someone recommended X — is it any good?" — the verdict for one skill by name, slug, or repo |
Every answer carries one of three verdicts:
If nothing has been tested for your job, the server says so instead of guessing. "Not tested" is a real answer.
Claude Code:
Or add it to your MCP config by hand:
Works in any MCP client (Claude Code, Claude Desktop, Cursor, Windsurf, Zed). Node 18+. No API key, no account.
The server reads the live catalog at skillproof.dev/api/skills.json
and caches it for 15 minutes. Nothing is bundled, so verdicts are never stale. The scoring rubric —
install /5, triggering /5, output-vs-baseline /10, docs /5 — is published at
skillproof.dev/methodology.
