Add MCP servers to LibreChat

LibreChat runs MCP servers on the server side of a self-hosted deployment: configure once and every user of your instance gets the tools.

The config LibreChat expects

Lives in: librechat.yaml

One entry per server, under the top-level mcpServers key:

{
  "mcpServers": {
    "your-server": {
      "command": "npx",
      "args": [
        "-y",
        "the-server-package"
      ]
    }
  }
}

Swap the placeholder for a real server: every server page on this site renders the exact block, ready to paste.

Prefer running nothing locally? Start from a hosted endpoint instead: the best remote MCP servers.

Quick answers

Where does LibreChat keep its MCP configuration?

In librechat.yaml. The official documentation covers edge cases and the newest options.

Do all MCP servers work with LibreChat?

Any server speaking standard MCP transports should work: local servers run as a process your client starts, remote servers are a URL you point it at. Each server page on this site shows its exact config, and states when a server needs credentials first.

About this page

Client mechanics come from each client's public documentation, linked above; anything we are not certain of defers to those docs rather than guessing. Server rankings are ours: monthly installs, GitHub stars, and commit recency, recomputed nightly. How we verify.
