Reference MCP servers for files, git, fetch, memory and time
Official collection of reference Model Context Protocol servers maintained by the MCP steering group: Everything, Fetch, Filesystem, Git, Memory, Sequential Thinking and Time. TypeScript servers start with npx and Python ones with uvx or pip. All serve stdio; only Everything also serves Streamable HTTP. The README states they are educational examples, not production-ready.
Strengths
- Maintained by the MCP steering group, so it tracks the spec and official SDKs
- Seven small servers covering files, git, web fetch, knowledge-graph memory and time
- Starts with one command: npx for TypeScript servers, uvx or pip for Python ones
- Everything server exercises prompts, resources and tools, and also serves Streamable HTTP
Weaknesses
- README says these are reference implementations, not production-ready
- Only Everything supports Streamable HTTP; the other servers are stdio only
- Many earlier servers (GitHub, Postgres, Slack, Redis and others) are archived
- License is reported as NOASSERTION: Apache-2.0 for new contributions, MIT for older code
- no GPU
- Needs Node.js (npx), uv or pip (Python servers), MCP client
