Core ComfyUI knowledge covering workflow format, node types, pipeline patterns, and MCP tool usage.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ComfyUI Core Knowledge

## Workflow JSON Format (API Format)

ComfyUI workflows are JSON objects mapping string node IDs to node definitions:

```json
{
  "1": {
    "class_type": "CheckpointLoaderSimple",
    "inputs": { "ckpt_name": "sd_xl_base_1.0.safetensors" },
    "_meta": { "title": "Load Checkpoint" }
  },
  "2": {
    "class_type": "CLIPTextEncode",
    "inputs": { "text": "a cat", "clip": ["1", 1] },
    "_meta": { "title": "Positive Prompt" }
  }
}
```

### Key Rules

- Node IDs are strings of integers (`"1"`, `"2"`, etc.)
- `class_type` is the exact Python class name of the node
- `inputs` contains both widget values (scalars) and connections (arrays)
- Connections use the format `["sourceNodeId", outputIndex]`, a 2-element array where:
  - the first element is the string node ID of the source node
  - the second element is the integer index into the source node's `output` list (0-based)
- `_meta` is optional and used for display titles only

### Connection Examples

```json
"model": ["1", 0]       // Connect to node 1's first output (MODEL)
"clip": ["1", 1]        // Connect to node 1's second output (CLIP)

How to install

The exact contents, by fingerprint
mdr add artokun/comfyui-mcp/comfyui-core@sha256:0cf77629c6b16834

The line at the top of this page pins the label git:20261025.d36a05c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
