Superseded by MSCH Nodes: one install for the complete collection.

This standalone repository is retained for historical links and existing installations. New nodes and updates belong to the unified pack. Follow the migration guide before switching to avoid duplicate nodes.

Installation

Clone into ComfyUI/custom_nodes:

git clone https://github.com/mariobilly/msch-mcp-bridge.git

Open a terminal in the cloned folder and install requirements using the same Python environment as ComfyUI:

python -m pip install -r requirements.txt

Windows portable, from ComfyUI_windows_portable:

.\python_embeded\python.exe -m pip install -r .\ComfyUI\custom_nodes\msch-mcp-bridge\requirements.txt

Restart ComfyUI and refresh the browser. Load a JSON workflow from examples/ and select the supplied demo input or your own media. Keep only one installed copy of each package to avoid duplicate node registrations.

Requirements and behavior

This is an interface extension with zero graph nodes. It supplies HTTP routes and a browser event bridge; it is not a standalone MCP protocol server. Routes inherit access to your ComfyUI server and do not add their own authentication. The browser must be connected for graph updates and edits.

See the extension guide for behavior and usage. This package has no graph-node render output.

Documentation and examples

docs/NODES.md documents every input, default, range, choice and output. examples/README.md explains which inputs and other nodes each workflow needs and how the included results were produced.

ComfyUI Manager

The release includes Comfy Registry metadata and a GitHub publishing action. Version 0.1.0 was uploaded successfully to Comfy Registry under publisher mariobilly on 2026-09-06. Registry reported Pending at verification; Manager installation availability is not yet confirmed. A separate ComfyUI Manager node-list registration has been submitted; listing is pending maintainer acceptance. Git installation works independently. See PUBLISHING.md.

Validation

Imports and input schemas were checked against the local ComfyUI environment with Python 3.12.10, PyTorch 2.10 and CUDA available. Example render coverage is documented per workflow; this is not a claim of compatibility testing on every platform or of full MiniMax H3 model-generation validation.
