install_comfyui
Install ComfyUI into an empty directory with Python dependencies and optional ComfyUI-Manager. Returns a detailed report upon completion.
Instructions
Install ComfyUI locally: git-clone it into a target directory, create a dedicated workspace virtualenv (/.venv), and install Python requirements INTO that venv (never the Python running this MCP server) via pip or uv. ComfyUI-Manager is installed from manager_requirements.txt when present, else git-cloned as a fallback. Mirrors comfy-cli install. LOCAL, subprocess-only and independent of any remote --comfyui-url target; the target dir must be empty or non-existent (an existing install is never overwritten). Runs SYNCHRONOUSLY and can take several minutes (large git clone + full torch/dependency install); the call blocks until done. On success returns a JSON report { installed, targetPath, venvPath, comfyuiUrl, managerInstalled, managerVia, version, pythonInstaller, steps[] }. Does NOT start ComfyUI.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| use_uv | No | If true, prefer `uv pip install` over plain pip when uv is available on PATH. Falls back to pip if uv is missing. Default false. | |
| version | No | ComfyUI version to install (comfy-cli semantics): "nightly" (default-branch HEAD), "latest" (newest release tag), or a semantic version like "0.3.40" (checked out as tag v0.3.40). Raw git refs/branches are rejected. Omit to track the default branch HEAD. | |
| target_path | Yes | Absolute path to the workspace directory to install ComfyUI into. Must be empty or non-existent. | |
| skip_manager | No | If true, do not clone/install ComfyUI-Manager. Default false (Manager is installed). |
