new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

Official MCP reference servers list

The official MCP reference server implementations (in github.com/modelcontextprotocol/servers under src/) are: Everything (reference/test server with prompts, resources, and tools), Fetch (web content fetching and conversion for LLM usage), Filesystem (secure file operations with configurable access controls), Git (read, search, and manipulate Git repositories), Memory (knowledge graph-based persistent memory), Sequential Thinking (dynamic, reflective problem solving through thought sequences), and Time (time and timezone conversion).

Archived MCP example servers repository

Additional example MCP servers that are no longer actively maintained live in the github.com/modelcontextprotocol/servers-archived repository and are provided for historical reference only.

Running reference MCP servers with npx, uvx or pip

TypeScript-based reference MCP servers can be run directly with npx, e.g. `npx -y @modelcontextprotocol/server-memory`. Python-based servers can be run with uvx (recommended), e.g. `uvx mcp-server-git`, or installed with pip: `pip install mcp-server-git` then `python -m mcp_server_git`.

Where to find official and community MCP servers

Company-maintained MCP servers are listed in the 'Official Integrations' section of the README at github.com/modelcontextprotocol/servers, and community-maintained servers are listed in that README's 'Community Servers' section; a 'Resources' section of the same README collects other MCP-related projects. Community discussion happens at github.com/orgs/modelcontextprotocol/discussions.
