## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 19 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 63/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 795 tokens (~132/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 63/100
  - Stability observed for 19 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (50% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

### How do I install the ComfyUI MCP server?

ComfyUI MCP runs locally as a container image, launched with docker run --rm -i -e COMFYUI_URL -e COMFYUI_PUBLIC_URL -e MCP_AUTH_TOKEN ghcr.io/germaniu/comfyui-mcp:0.1.1 --stdio. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

### Claude

## MCP tools (6)

### `generate_image` (~238 tokens)

Generate Image

Genera imágenes en la RTX 3060 (SDXL vía ComfyUI). Presets: producto (fotorrealista marketing), realista (versátil), rapido (borradores ~5s), anime (checkpoint no disponible). Devuelve filename+subfolder en Pop!_OS (pedir con comfy_view_url para la URL directa de descarga). La primera generación con un checkpoint tarda ~1 min extra por carga del modelo, más ~10-30s si hay que despertar el servicio (switch de GPU con el LLM). Prompt en inglés funciona mejor. preview=true devuelve además una miniatura JPEG (~512px) para ver el resultado; solo en clientes con visión.

Input parameters:

- `aspect` (string)
- `batch` (integer)
- `cfg`
- `checkpoint`
- `detail_face` (boolean)
- `filename_prefix` (string)
- `lora`
- `lora_strength`
- `negative_prompt`
- `preset` (string)
- `preview` (boolean)
- `prompt` (string, required)
- `seed`
- `steps`

### `list_models` (~37 tokens)

List Models

Lista checkpoints, loras y presets disponibles en ComfyUI. Si ComfyUI está dormido devuelve solo los presets, sin despertarlo.

Output parameters:

- `result` (string)

### `comfy_health` (~31 tokens)

Comfy Health

Estado de ComfyUI: si responde, VRAM libre/total de la GPU y tamaño de la cola.

Output parameters:

- `result` (string)

### `comfy_view_url` (~51 tokens)

Comfy View Url

Devuelve la URL LAN de descarga directa para una imagen o video ya generado (por filename).

Input parameters:

- `filename` (string, required)
- `img_type` (string)
- `subfolder` (string)

Output parameters:

- `result` (string)

### `img2img` (~194 tokens)

Img2Img

Varía una imagen ya generada usando img2img. Pasar image_filename (ej: test_00001_.png) y denoise (0.0=idéntica, 1.0=completamente nueva, 0.3-0.7 recomendado). Si prompt está vacío, hace variación visual pura. Útil para iterar un arte sin partir de cero o generar variaciones de memes. preview=true devuelve además una miniatura JPEG; solo en clientes con visión.

Input parameters:

- `cfg`
- `checkpoint`
- `denoise` (number)
- `filename_prefix` (string)
- `image_filename` (string, required)
- `lora`
- `lora_strength`
- `negative_prompt`
- `preset` (string)
- `preview` (boolean)
- `prompt` (string)
- `seed`
- `steps`

### `generate_video` (~244 tokens)

Generate Video

Genera un clip corto (1-5s, 24fps, MP4) con Wan 2.2 en la RTX 3060. Sin image_filename es txt2video; con image_filename (una imagen ya generada, ej: mcp_00001_.png) la anima usándola como primer frame — conviene que su aspect coincida con el del video. aspect: 16:9, 9:16 o 1:1. Tarda varios minutos (más la primera vez por carga del modelo); describir la escena y el movimiento de cámara en inglés. draft=true genera a ~480p, bastante más rápido: útil para probar el prompt antes de la versión final. Devuelve filename + URL de descarga. preview=true devuelve además una miniatura JPEG del primer frame.

Input parameters:

- `aspect` (string)
- `cfg`
- `draft` (boolean)
- `filename_prefix` (string)
- `image_filename`
- `negative_prompt`
- `preview` (boolean)
- `prompt` (string, required)
- `seconds` (integer)
- `seed`
- `steps`

## Common questions

### What is the ComfyUI MCP server?

ComfyUI MCP is listed in the public MCP registry as io.github.GermaniU/comfyui-mcp. MCP server that wraps ComfyUI (SDXL/Wan 2.2) for image and short-video generation. This page covers its container image (ghcr.io/germaniu/comfyui-mcp).

### Is the ComfyUI MCP server safe to use?

ComfyUI MCP scores 45 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the ComfyUI MCP server expose?

ComfyUI MCP exposes 6 tools: generate_image, list_models, comfy_health, comfy_view_url, img2img, generate_video. Their descriptions and schemas cost roughly 795 tokens of context every time the server is loaded.

### Is the ComfyUI MCP server still maintained?

ComfyUI MCP is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the ComfyUI MCP server under?

ComfyUI MCP declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the ComfyUI MCP server?

VerifyMCP ran 12 checks on ComfyUI MCP, covering Source repository, Provenance, License, Maintenance and 8 more. 4 items could not be completed, a gap on our side rather than a finding about ComfyUI MCP: Malware scan, Known CVEs, Install scripts and Dependency health. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to a container image, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
