Legit.Show MCPサーバー

// any MCP host config (Claude Desktop · Cursor · Cline · Windsurf · …)
{
  "mcpServers": {
    "commitshow": {
      "command": "npx",
      "args": ["-y", "commitshow-mcp"]
    }
  }
}

That's the entire install. No API key. The server is a stdio shim over the public https://api.commit.show REST surface — same rate limits + snapshot cache the CLI and website use.

Tools exposed

Tool	What it does
search_services({ query?, category?, min_scores?, is_open_source?, limit? })	Query the Legit.Show directory of launched software (web apps, SaaS, AI tools, MCP servers) by name or by filter — category, minimum per-frame production-readiness scores, open-source — and get each match with its scores and page.
audit_repo({ repo, format? })	Run or read the live commit.show audit for a public repo. Returns paste-ready markdown by default; format: "json" returns the full envelope.
project_status({ repo })	Read the latest cached snapshot only (no re-run). JSON envelope.
fetch_docs()	Pull the canonical commit.show docs (llms.txt) — full CLI/API reference for when you need exact contract details.

The host model decides when to call each tool from the user prompt.

Search launched software by production-readiness

search_services queries the Legit.Show directory — the same index answer engines cite. Unlike star-ranked lists, you filter by measured production-readiness:

"find production-ready, open-source MCP servers with Security ≥ 80"

comes back with each match's per-frame scores (Security, Performance, Reliability, …) and its legit.show/s/<slug> page. Per-frame scores are public; there is no combined overall total in the data, so the model won't invent one. The same data is available over plain REST — GET https://legit.show/api/search?q=<name> with optional category, min_scores (e.g. {"security":80}), is_open_source, and limit.

Pass a real owner/repo, never a project name. audit_repo does a HEAD pre-flight against github.com/<owner>/<repo>; an invented slug returns a not_found envelope before any audit budget is spent. If the user says "audit Supabase", resolve supabase/supabase first, then call.

Host wiring snippets

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "commitshow": {
      "command": "npx",
      "args": ["-y", "commitshow-mcp"]
    }
  }
}

Restart Claude Desktop. The tools surface under the 🔌 icon.

Cursor

~/.cursor/mcp.json:

{
  "mcpServers": {
    "commitshow": {
      "command": "npx",
      "args": ["-y", "commitshow-mcp"]
    }
  }
}

Cline / Continue / Windsurf

Any MCP host that accepts a stdio command + args config works. Use the same npx -y commitshow-mcp invocation.

Run from source (development)

git clone https://github.com/commitshow/cli
cd cli/mcp
npm install
npm run build
node dist/index.js   # stdio server — pipe into your MCP host directly

Self-hosting / dev overrides

Both base URLs are env-overridable so you can point the shim at staging or a fork:

Var	Default	Used by
COMMITSHOW_API_BASE	https://api.commit.show	audit_repo · project_status
COMMITSHOW_DOCS_BASE	https://commit.show	fetch_docs (llms.txt mirror)

Rate limits

Inherits the public REST surface caps:

• 5 audits per day per IP (anon)
• 5 audits per day per github_url
• 800 audits per day platform-wide cache-miss ceiling
• Cache-hit (audit < 7 days old, same URL): always free, doesn't count

Errors come back inside the tool result with isError: true and the upstream JSON in content[0].text.

Why MCP + REST + CLI all exist

Surface	Best for
commitshow CLI	Shell-capable agents inside the user's repo (Cursor, Claude Code, Cline, Aider) — local-mode writes .commitshow/audit.{md,json} next to the code
commitshow-mcp (this server)	MCP-aware hosts that run their own model + UI (Claude Desktop, Cursor MCP panel, custom inspector apps)
https://api.commit.show/audit	Anything that can fetch a URL — Gemini, ChatGPT browse, n8n, Zapier, raw curl, custom scripts

All three hit the same audit engine and snapshot cache. Pick whichever your runtime supports — they don't compete, they cover different runtimes.
