From GitHub's daily star counts.
Checked on GitHub.
Overview
Go implementation of the MCP Registry, an HTTP API that gives MCP clients a catalog of published MCP servers. It stores data in PostgreSQL and ships an mcp-publisher CLI that publishes server.json entries, verifying namespace ownership via GitHub OAuth, GitHub OIDC, or DNS/HTTP challenges. The v0.1 API is under a freeze, and the project is still a preview release.
Who it is for: MCP server authors and teams running or integrating an MCP server catalog
Strengths
- Namespace ownership checks via GitHub OAuth, GitHub OIDC, DNS or HTTP verification
- Includes mcp-publisher CLI for publishing server.json entries
- One command (make dev-compose) starts a dev stack seeded from the production API
- Pre-built images published to GitHub Container Registry
Weaknesses
- Preview release; README warns of breaking changes or data resets before GA
- Image does not bundle PostgreSQL; you must run and configure your own
- Dev compose database is ephemeral and resets on every restart
- Servers cannot be published through pull requests to this repo
What it needs
- no GPU
- Compose
- Needs PostgreSQL, Docker, ko
- port 8080
