What this is

Model Context Protocol servers let AI agents talk to real systems — databases, browsers, filesystems, APIs. There are thousands of them, scattered across GitHub repos with inconsistent READMEs and no common way to search or compare them.

AllMCPs is the directory that fixes that. It catalogs 22,000+ MCP servers with semantic search, category browsing, health checks, and a copy-paste install config for every listing.

• Search and browse across 50+ categories, with per-listing detail pages covering install steps, tools exposed, and upstream health.
• Free browser tools — config generator and validator, protocol inspector, token calculator, OpenAPI-to-MCP converter, and a playground.
• Agent-native — every listing has a copy-paste agent prompt, and the site exposes llms.txt, an MCP server of its own, and DNS-based agent discovery.
• Claim and verify — maintainers prove ownership of a repo or domain and edit their own listings.

[!NOTE] Adding a server doesn’t need a pull request. Listings live in a database — submit at allmcps.com/submit, and claim an existing listing from its page to edit it.

Quick start

Requires Node 22 (see .nvmrc).

bun install
bun run dev

Open localhost:3000. No Cloudflare account, database, or API key is needed to run the site locally.

In next dev there are no Cloudflare bindings, so data comes from data/mcp-servers.json — a sample catalog of ~113 listings spanning every category, enough to work on essentially any page. In production the same code paths read from D1 and fall back to that file on error (see lib/servers.ts).

To work against the full catalog locally, rebuild it from the public source lists — and don’t commit the result:

node scripts/seed.mjs

Contributing

Contributions are welcome — see CONTRIBUTING.md for setup, the checks a change has to pass, and the conventions that aren’t obvious from the code.

Two worth knowing up front:

• This is not the Next.js you may know. The project tracks a newer release with breaking changes. Read the bundled guides in node_modules/next/dist/docs/ before writing routing or rendering code. See AGENTS.md.
• UI work follows BRAND_GUIDE.md — colors, typography, and logo usage.

Please read the Code of Conduct before participating, and report security issues privately per SECURITY.md.
