MCP server

Tool-based access to every vetted loop in the directory — plus the same A–F safety grader that curates it. No auth, no API key; read tools are open, rate limit 60 req/min per IP.

Install

Claude Code:

claude mcp add --transport http looprepo https://mcp.looprepo.dev/mcp→ Claude

Cursor / Windsurf / VS Code — add to your MCP config:

{
  "mcpServers": {
    "looprepo": { "url": "https://mcp.looprepo.dev/mcp" }
  }
}→ Claude

Tools

looprepo_search_loops — search the catalog by text, category, loop type, or safety grade
looprepo_get_loop — fetch one loop’s full prompt and stopping conditions by slug
looprepo_list_categories — list categories with live counts
looprepo_grade_prompt — grade any loop prompt A–F with the same deterministic, default-fail gate that curates this directory
looprepo_generate_harness — generate a complete safe-loop harness bundle (requires an email; 30/day per email, 3/hour per network)

auth discovery — declares the server open (no authorization servers)

Prefer plain HTTP? The catalog is also directly fetchable — see the agents page for catalog.json, catalog.txt and llms.txt. Want to check a loop before running it? Grade it →
