Install Buildkite in mcp-client-cli

What you need first

• mcp-client-cli, installed.
• Docker, which gives the docker command the server starts with.
• Your own value for YOUR_BUILDKITE_API_TOKEN.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "mcpServers": {
    "buildkite-mcp-server": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "BUILDKITE_API_TOKEN", "ghcr.io/buildkite/buildkite-mcp-server:0.7.0"],
      "env": { "BUILDKITE_API_TOKEN": "YOUR_BUILDKITE_API_TOKEN" }
    }
  }
}

3. Replace YOUR_BUILDKITE_API_TOKEN with your own value.
4. Save the file and restart mcp-client-cli.

Check it worked

Ask mcp-client-cli: List the tools of buildkite-mcp-server.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart mcp-client-cli.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
