## Description
Generate and manage ComfyUI media through the Model Context Protocol.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "comfyui-mcp": {
    "command": "npx",
    "args": ["-y","comfyui-mcp"]
  }
}
```

Give an AI agent access to ComfyUI generation, workflows, installed models,
recent assets, and job controls through the Model Context Protocol.

## Quickstart

### 1. Install .NET 10

Install the [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0).
The SDK includes `dnx`, which downloads and runs the pinned NuGet package
without a permanent installation.

Start ComfyUI normally and leave it available at `http://localhost:8188`.

### 2. Paste the server configuration

Add this server to your MCP configuration:

```json
{
  "mcpServers": {
    "comfyui": {
      "command": "dnx",
      "args": [
        "ComfyUi.Mcp@0.0.1-preview5",
        "--yes",
        "--",
        "--stdio"
      ]
    }
  }
}
```

See [MCP client configuration](docs/mcp-configuration.md) for a complete
configuration and copy-paste alternatives, including connecting to ComfyUI at
another URL.

Some clients call the top-level property `servers` instead of `mcpServers`.
Restart or refresh the MCP client after saving the configuration.

### 3. Let your agent finish setup

Ask:

> Run `setup_guide()` and help me configure ComfyUI MCP.

The guide discovers installed models and bundled workflow families, then helps
the agent choose workflows and create reusable defaults. The server can start
while ComfyUI is offline, but model discovery and generation require ComfyUI to
be running.

## Setup guide

For a more deliberate first setup, ask your agent to:

1. Run `setup_guide()`.
2. Run `workflow_list()` and show workflows that match your installed models.
3. Run `family_list()` and `family_model_list()` to check model associations.
4. Run `workflow_options_show()` before the first execution.
5. Save any defaults you approve with `workflow_config_set()`.
6. Generate a small test image and display it with `image_show()`.

Workflow JSON defines the available parameters. Optional YAML layers provide
reusable family, workflow, and model defaults. Tool-call values always have the
highest precedence. See [Configuration](docs/configuration.md) for the complete
model.

## Features and usage

### Families

Families group compatible installed models and enable random selection.

- `family_list()` discovers configured families.
- `family_model_list()` shows installed members.
- `family_model_add()` and `family_model_remove()` maintain exact membership.

Try asking: “Show my configured families and which installed models belong to
each one.”

### Workflows

Bundled workflows cover image, audio, video, editing, upscaling, interpolation,
and text generation.

- `workflow_list()` discovers workflow IDs.
- `workflow_options_show()` resolves inputs, defaults, and allowed values.
- `workflow_execute()` runs any parameterized workflow.
- `workflow_config_set()` saves reusable defaults.

Try asking: “List the workflows I can run, then explain the options for the
best text-to-image workflow.”

### Models

`model_list()` reads the current checkpoint and diffusion-model inventory
directly from ComfyUI. Exact model requests must use the returned filename,
including its extension.

Try asking: “List my installed models and recommend compatible workflow
families without inventing filenames.”

### Assets

Generated outputs and their provenance are stored in a bounded SQLite registry
that survives MCP server restarts.

- `asset_list()` and `asset_show()` inspect recent outputs.
- `generation_show()` follows durable event-driven generation state.
- `image_show()` renders an image in the conversation.
- `asset_regenerate()` reuses a submitted workflow with new parameters.
- `asset_publish_info()` and `asset_publish()` copy outputs into a project.

Try asking: “Show my five most recent assets and display the newest image.”

### ComfyUI

The server can upload inputs and manage ComfyUI jobs directly.

- `comfy_media_upload()` stages image, audio, or video inputs.
- `comfy_queue_status_show()` reports running and pending jobs.
- `comfy_job_show()` reads local state for a prompt submitted by this server.
- `comfy_job_cancel()` cancels queued or running work.

Try asking: “Show the ComfyUI queue and explain what is currently running.”

- [Edit an image](docs/how-to/image_edit.md)

- [Generate video from text](docs/how-to/text_to_video.md)
- [Interpolate video frames](docs/how-to/video_frame_interpolation.md)

## Tips and tricks

### Pick a random model from a family

Ask the agent to call `family_model_list()` first, then use
`model_strategy: random` with the chosen family:

```json
{
  "prompt": "A cinematic city at dusk",
  "workflow_id": "image_krea2_turbo_t2i",
  "family": "krea2-turbo",
  "model_strategy": "random",
  "aspect_ratio": "16:9"
}
```

The server selects only from installed models associated with that family.

### Add `readme()` to your system prompt

The `readme()` tool returns compact operating instructions for agents, including
workflow discovery, exact model selection, media upload, and image display.
Call it once and add the returned text to your agent's system prompt or
persistent project instructions. `read_skill()` is an alias.
