Set up

Runs locally

This server runs on your machine, so the install command depends on its package. The project docs has the exact steps. Most clients expect an entry shaped like this:

mcp.json
{
  "mcpServers": {
    "langgraph": {
      "command": "<command from the docs>",
      "args": [
        "<args>"
      ],
      "env": {}
    }
  }
}
