About Comfy Pilot

Comfy Pilot is a ComfyUI custom node that bridges Claude Code and ComfyUI via an MCP server over stdio and an embedded terminal. It lets you describe workflows in natural language while Claude views the current graph, creates and connects nodes, runs the workflow, inspects generated images, manages custom nodes, and downloads models. The MCP server is configured automatically when ComfyUI starts.

What this server can do

Comfy Pilot provides tools for these capabilities — tap one to see every MCP server that does the same:

Generate images

When to use it

Build a complete workflow (e.g. an SDXL workflow with ControlNet) from a natural-language description.
Inspect a generated preview image and have Claude adjust the workflow for more detail.
Download a model (e.g. FLUX.1 schnell) and set up a workflow for it from scratch.
Search for and install custom nodes from the ComfyUI Manager registry without leaving the chat.
Run a workflow up to a specific node and review queue status and execution history.

Security notes

The plugin runs the Claude Code CLI as a PTY process inside ComfyUI and exposes tools that can edit workflows, install custom nodes, and download models to your machine. The MCP server runs locally over stdio with no authentication; only use it with a ComfyUI instance you trust. The download_model tool can fetch gated Hugging Face models using a token if provided.

Comfy Pilot FAQ

How do I install it?

Use the ComfyUI CLI with `comfy node install comfy-pilot`, install via ComfyUI Manager by searching for "Comfy Pilot", or git clone the repo into ComfyUI's custom_nodes folder. Restart ComfyUI afterward.

Do I need to configure the MCP server manually?

No. The plugin auto-configures MCP for Claude Code on startup. If it isn't connecting, you can manually add the comfyui server to ~/.claude.json with command python3 and args pointing to mcp_server.py.

The terminal says 'Command claude not found'. What do I do?

Install the Claude Code CLI. On macOS/Linux/WSL run `curl -fsSL https://claude.ai/install.sh | bash`; on Windows use the PowerShell or CMD installer from claude.ai.

Where do downloaded models go?

The download_model tool downloads models to your ComfyUI models folder and supports Hugging Face (including gated models with token auth), CivitAI, and direct download URLs.
