fx - Kernel

Install with the Kernel CLI

Run the following command:

kernel mcp install --target fx

Alternatively, add Kernel to the mcp map in ~/.fx/mcp.json:

{
  "mcp": {
    "kernel": {
      "type": "http",
      "url": "https://mcp.onkernel.com/mcp",
      "oauth": {}
    }
  }
}

Start fx, or reload the configuration in an existing session:

/mcp reload

Then authenticate with Kernel:

/mcp auth kernel --open

Authorize access in the browser window that opens. You can then run /mcp list to verify that Kernel is connected.
