Model Context Protocol servers
Smithery reference servers mcp server connects Smithery Reference Servers to AI assistants that speak the Model Context Protocol. Model Context Protocol servers.
This repository is a collection of reference implementations for the Model Context Protocol (MCP), as well as references to community built servers and additional resources.
The server is distributed via npm as @modelcontextprotocol/server-memory, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Before the server will start you need to supply 2 environment variables: GITHUB_PERSONAL_ACCESS_TOKEN, YOUR_TOKEN. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Smithery Reference Servers sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
