# The MCP tools

`noodlelab mcp` serves these tools over the Model Context Protocol (stdio). Add
it to an agent with one of:

```bash
claude mcp add noodlelab -- uvx noodlelab mcp   # Claude Code
codex mcp add noodlelab -- uvx noodlelab mcp    # Codex CLI
noodlelab init-agent                            # writes .mcp.json, and more
```

It works on the graphs in its workspace folder (the current folder, or
`--workspace`). Started from the editor's Agent panel, it saves through the
editor instead, which reloads each graph as the agent saves it.
