- What is the Model Context Protocol?
- MCP is an open standard, introduced by Anthropic, for connecting large language models to external tools and data sources via a uniform protocol. Servers expose tools, resources, and prompts; clients (like Claude Desktop) consume them.
- How do I submit a server?
- Sign in and visit /submit, paste a GitHub repo URL, and confirm the auto-detected metadata. We review within 48 hours.
- How do I get featured?
- Submit your server, then on its detail page click 'Promote' (or visit /pricing). Featured listings appear on the homepage and at the top of their category. $39/mo, cancel anytime.
- What's the refund policy?
- Featured subscriptions are refundable within 7 days of the first payment. After that, you can cancel at any time and keep the placement until the period ends.
- Is there an API?
- Yes — a read-only public API at /api/v1. Rate-limited at 60 requests/minute per IP. See /api/docs.
- How often is the catalog refreshed?
- Every Sunday at 03:00 UTC we re-sync stars, forks, last commit, and READMEs for all approved servers.
- Can I report incorrect information?
- Each server page has a 'Suggest a correction' link. We action reports within a few business days.
