MCP Registry

Official open catalog of Model Context Protocol servers

open sourceupdated Jul 26, 2026

The official, community-run registry for discovering and publishing Model Context Protocol (MCP) servers — an open index that MCP clients read to find available servers.

MCP Registry is the canonical directory service governed under the Model Context Protocol project. It gives MCP client apps a machine-readable list of published MCP servers, and gives server authors a single place to publish metadata. *Vendor-described* purpose: the README frames it as "an app store for MCP servers." The practical value is a neutral, standards-aligned source of truth rather than a proprietary marketplace — you can consume the free hosted public API (`registry.modelcontextprotocol.io`) or run your own instance behind your firewall. Publishing is via a CLI or web interface. As of its post-preview release the API is in a v0.1 freeze, so integrators get a stable-ish contract but should expect the schema to evolve. It is infrastructure/plumbing, not an end-user product — evaluate it as a data source and self-host option, not a dashboard.

Pricing

Free. Public hosted registry API is free to query; self-hosting (Docker/Go) carries only your own infra cost. No license fees, no paid tiers.

Platforms

Hosted public HTTP API (`/v0/servers`) for discovery; self-hostable via Docker or Go source; server publishing via official CLI or web UI. Cross-platform (Go service).
