About

MCP Catalog

The directory of MCP servers for Claude, Cursor, and AI coding tools.

What is MCP Catalog?

MCP Catalog is a directory of Model Context Protocol servers — the small adapter programs that let AI tools like Claude, Cursor, and other coding assistants talk to real systems: your filesystem, GitHub, Postgres, Slack, Linear, Stripe, and so on.

If you've ever wished your AI assistant could actually do the thing instead of just describing how to do it, MCP is the missing connector. This site exists to help you find the right one quickly.

What is MCP, in 60 seconds?

The Model Context Protocol is an open standard (originally proposed by Anthropic, now broadly adopted) for connecting language models to external tools and data sources. The model talks to an MCP client — that's your IDE or chat app — which spawns or connects to MCP servers. Each server exposes some capability: tools the model can call, resources it can read, or prompts it can use.

The win is composability. Instead of every assistant building its own connectors to every service, anyone can publish an MCP server and any compliant client can use it. Plug in a Postgres server and Claude can run queries. Plug in a GitHub server and Cursor can open PRs. Same protocol, different surfaces.

Why a directory?

Because finding the right MCP server today involves searching across:

  • The official modelcontextprotocol/servers repo
  • A growing pile of community servers scattered across GitHub
  • Vendor blogs announcing first-party integrations
  • Random Twitter threads

That's not a great experience. MCP Catalog indexes them in one place, with consistent metadata, working install commands, and a search that actually understands developer terminology.

How servers get listed

We add servers two ways:

  1. Curated — for the official Anthropic-maintained ones and big vendor integrations (Stripe, GitHub, Linear, etc.), we add them ourselves and keep them up to date.
  2. Submitted — anyone can submit a server. We review every submission, check the repo is real and maintained, and publish the ones that meet the bar.

There is no pay-to-play. Featured slots on the homepage are editorial picks, not paid placements. (We'll be transparent if that ever changes.)

What's not here yet

Honest list:

  • Reviews and ratings. Today we only show GitHub stars as a rough quality signal. Proper reviews are coming.
  • One-click install. We show install commands; we don't yet write them into your client config for you. Cursor, Claude Desktop, and Continue all do this differently and we want to nail it before shipping.
  • Self-hosted server hosting. Out of scope for now — there are good options elsewhere (Railway, Fly, Cloudflare Workers).

Tech, briefly

MCP Catalog is built with Next.js 15 App Router, Drizzle ORM on Turso (libSQL), Tailwind CSS v4, and shadcn/ui. The directory is statically generated with ISR so individual server pages are fast and rank well. Search is client-side via Fuse.js — fast even on flaky connections, no round-trip per keystroke.
