## What it is
A community-driven registry service for Model Context Protocol (MCP) servers, acting like an app store where MCP clients can discover servers and publishers can list theirs. It exposes a REST API (currently in v0.1 API freeze) and is developed in Go by the MCP Registry Working Group.

## Use cases
- discover MCP servers for my AI client
- publish my MCP server to a public registry
- query the MCP registry API for server metadata
- find Model Context Protocol servers by name or capability
- integrate MCP server discovery into an MCP client
- look up server. metadata for MCP servers

## When to choose
- you are building an MCP client and need a canonical source of available MCP servers
- you want to publish your MCP server so users can discover it
- you need a stable, spec-backed API for MCP server metadata

## When to avoid
- you need a private, self-hosted MCP server catalog with full control (the public registry is the primary offering)
- you require a fully GA-guaranteed API, since the registry is still in preview with possible breaking changes or data resets before v1

## Facets
- artifact type: service
- maturity: active
- function: mcp, search-engine, api-framework, self-hosted
- domain: artificial-intelligence, developer-tools, apis
- platform: go, cloud
- tags: mcp-registry, mcp-servers, server-discovery, app-store, api-freeze, ai-agents, docker, web-server
