3. modelcontextprotocol/typescript-sdk - 13,024 stars. TypeScript SDK.
4. modelcontextprotocol/specification - 8,799 stars. The protocol spec itself.

Community favorites (8)

Priority tiers

First install (official reference servers): filesystem, GitHub, PostgreSQL (read-only), memory. Second (on demand): Git, Slack, browser automation, search. Third: build your own with the SDKs.

Run in 2 minutes

uvx mcp-server-git --repository /path/to/repo

Then add the server to your MCP-capable agent client.

Security

Official servers prompt for permission; review community server source before granting credentials. Prefer read-only DB config and restrict filesystem scope.

FAQ

Q: One server per tool? A: No - one server exposes many tools, and SaaS tools like Slack and Notion ship official MCP servers. Q: Are MCP servers secure? A: Official ones prompt for permission; audit community servers first. Q: Where to start? A: Filesystem + GitHub servers from the official collection.

❓ FAQ

Do I need a server for every tool?

No - one server can expose many tools, and many SaaS tools (Slack, Notion) now ship official MCP servers.

Are MCP servers secure?

Official ones prompt for permission; review community servers before giving them credentials.
