Security Scan

The skill's requirements and instructions are coherent with an image-generation toolkit, but it relies on running a pinned npm package via npx at runtime—this is expected for Node-based MCP servers but carries moderate risk that you should review before use.

Purpose & Capability

The declared binaries (mcporter, npx, node) and the instructions to run a pinned meigen npm package match the stated purpose of routing image generation across providers and managing ComfyUI workflows. Requested resources and referenced config paths (e.g., ~/.config/meigen/config.json, ~/.clawdbot/.env, comfyuiUrl) are appropriate for an image-generation MCP server.

Instruction Scope

SKILL.md stays within the image-generation domain: it tells the agent how to register the MCP server, how to call tools, and where to store provider credentials. It does instruct the agent to read/write user config files in the home directory (e.g., ~/.config/meigen/config.json and ~/.clawdbot/.env) which is consistent with storing API tokens and preferences but is something to be aware of because those files may contain sensitive data.

Install Mechanism

There is no install spec bundled with the skill; instead the runtime workflow uses npx to execute meigen@1.2.10 from the npm registry. Running code fetched dynamically from npm is a common pattern but carries moderate risk because arbitrary JS runs on your machine. The package is pinned to a specific version (1.2.10) and the SKILL.md points to the public npm/GitHub repo, which reduces but does not eliminate risk—you should audit the package source or confirm trust in the upstream author before running.

Credentials

The skill itself does not declare required env vars, and the provider credentials it references (MEIGEN_API_TOKEN, openaiApiKey, comfyuiUrl) are reasonable and proportional to the stated tasks. There are no unrelated or excessive credential requests. The SKILL.md documents storing tokens locally and recommends file permission settings (chmod 600).

Persistence & Privilege

The skill does not request always:true or any elevated platform-wide persistence. It instructs the user to add a server entry to their mcporter config and to store provider tokens in conventional config files; these are standard and scoped to the skill's operation.

Assessment

This skill appears to do what it says: run a Node-based MCP server that routes image generation requests to multiple providers. Before installing/using it, verify the upstream npm package (meigen@1.2.10) and its GitHub repo to ensure you trust the author and version. Because the workflow runs code fetched by npx, consider auditing the package source or running it in a restricted/sandboxed environment. Only supply provider API tokens you intend to use; store them with restricted file permissions and avoid putting unrelated secrets into the same config files. If you need higher assurance, prefer using a local ComfyUI instance (keeps image data and models local) or host the meigen server in an isolated VM/container. If you want a deeper assessment, provide the meigen npm package contents (or its repository snapshot) for code review—that would change my confidence to high.

Creative Toolkit

Generate professional AI images through a unified interface that routes across multiple providers. Search curated prompts, enhance ideas into production-ready descriptions, and manage local ComfyUI workflows — all from a single MCP server.

Quick Start

Add the MCP server to your mcporter config (~/.config/mcporter/config.json):

{
  "mcpServers": {
    "creative-toolkit": {
      "command": "npx",
      "args": ["-y", "meigen@1.2.10"]
    }
  }
}

Free tools (search, enhance, inspire) work immediately — no API key needed:

mcporter call creative-toolkit.search_gallery query="cyberpunk"
mcporter call creative-toolkit.enhance_prompt brief="a cat in space" style="realistic"

To unlock image generation, configure one of these providers:

Provider	Config	What you need
MeiGen Cloud	MEIGEN_API_TOKEN	Token from meigen.ai (avatar → Settings → API Keys)
Local ComfyUI	comfyuiUrl	A running ComfyUI instance — no external API needed
Any OpenAI-compatible API	openaiApiKey + openaiBaseUrl + openaiModel	Your own key from Together AI, Fireworks AI, etc.

Set credentials in ~/.clawdbot/.env, ~/.config/meigen/config.json, or add an "env" block to the mcporter config above. See references/providers.md for details.

Available Tools

Free — no API key required

Tool	What it does
search_gallery	Semantic search across 1,300+ AI image prompts. Supports category filtering and curated browsing. Returns prompt text, thumbnails, and metadata.
get_inspiration	Get the full prompt and high-res images for any gallery entry. Use after search_gallery to get copyable prompts.
enhance_prompt	Expand a brief idea into a detailed, style-aware prompt with lighting, composition, and material directions. Supports realistic, anime, and illustration styles.
list_models	List all available models across configured providers with capabilities and supported features.

Requires configured provider

Tool	What it does
generate_image	Generate an image from a text prompt. Routes to the best available provider. Supports aspect ratio, seed, and reference images.
generate_image (with local paths)	Pass local file paths directly in referenceImages — images are auto-compressed locally (max 2MB, 2048px) and prepared for the selected provider. ComfyUI handles local files entirely within the local workflow.
comfyui_workflow	List, view, import, modify, and delete ComfyUI workflow templates. Adjust steps, CFG scale, sampler, and checkpoint without editing JSON.
manage_preferences	Save and load user preferences (default style, aspect ratio, style notes, favorite prompts).

Important Rules

Never describe generated images

You cannot see generated images. After generation, only present the exact data from the tool response:

**Direction 1: Modern Minimal**
- Image URL: https://images.meigen.art/...
- Saved to: ~/Pictures/meigen/2026-02-08_xxxx.jpg

Do NOT write creative commentary about what the image "looks like".

Never specify model or provider

Do NOT pass model or provider to generate_image unless the user explicitly asks. The server auto-selects the best available provider and model.

Midjourney V7 vs Niji 7

Both cost 15 credits, take ~60s, accept 1 reference image, and return 4 candidate images per generation. Advanced params (stylize/chaos/weird/raw/iw/sw/sv) run with fixed server-side defaults and cannot be tuned from MCP — the only exception is sref, settable via --sref <code> at the end of the prompt (Midjourney style codes only, e.g. 3799554500; no URLs or local paths). They differ in content focus and prompt enhancement style:

• Midjourney V7 (model: "midjourney-v7") — general / photorealistic. Use for product photography, portraits, landscapes, cinematic and editorial shots. When enhancing, use style: 'realistic' (the default).
• Midjourney Niji 7 (model: "midjourney-niji7") — anime / illustration ONLY. Do NOT use for photorealistic, product, or non-anime content — use GPT Image 2.0 or Nanobanana 2 instead. The server auto-appends anime illustration style if your prompt lacks anime keywords. When enhancing, ALWAYS pass style: 'anime' to enhance_prompt — the default realistic produces prompts poorly suited for anime models.

Always confirm before generating multiple images

When the user wants multiple variations, present options first and ask which direction(s) to try. Include an "all of the above" option. Never auto-generate all variants without user confirmation.

Workflow Modes

Mode 1: Single Image

User wants one image. Write a prompt (or call enhance_prompt if the description is brief), generate, present URL + path.

Mode 2: Prompt Enhancement + Generation

For brief ideas (under ~30 words, lacking visual details), enhance first:

1. enhance_prompt brief="futuristic city" style="realistic"
   -> Returns detailed prompt with camera lens, lighting, atmospheric effects

2. generate_image prompt="<enhanced prompt>"
   -> Omit aspectRatio to let MeiGen auto-infer (recommended). Pass an explicit
      value like aspectRatio="16:9" only when the user asked for that ratio.

Mode 3: Parallel Generation (2+ images)

User needs multiple variations — different directions, styles, or concepts.

1. Plan directions, present as a table
2. Ask user which direction(s) to try
3. Write distinct prompts for each — don't just tweak one word
4. Generate selected directions (max 4 parallel for API providers, 1 at a time for ComfyUI)
5. Present URLs + paths

Mode 4: Multi-Step Creative (base + extensions)

User wants a base design plus derivatives (e.g., "design a logo and make mockups").

1. Plan 3-5 directions, ask user which to try
2. Generate selected direction(s)
3. Present results, ask user to approve or try another
4. Plan extensions using the approved Image URL as referenceImages
5. Generate extensions

Never jump from plan to generating everything at once.

Mode 5: Edit/Modify Existing Image

User provides an image and asks for changes (add text, change background, etc.).

• Pass the image (URL or local path) as referenceImages, then generate with a short, literal prompt describing ONLY the edit
• The reference image carries all visual context — do NOT re-describe the original image
• Example prompt: "Add the text 'meigen.ai' at the bottom of this image"

Mode 6: Inspiration Search

1. search_gallery query="dreamy portrait with soft light"
   -> Finds semantically similar prompts with thumbnails

2. get_inspiration id="<entry_id>"
   -> Get full prompt text — copy and modify for your own generation

Mode 7: Reference Image Generation

Use an existing image to guide visual style. Pass URLs or local file paths directly to referenceImages.

generate_image prompt="coffee mug mockup with this logo" referenceImages=["~/Desktop/my-logo.png"]
   -> Local files are auto-compressed (max 2MB, 2048px) and prepared for the selected provider

Reference image sources: gallery URLs, previous generation URLs, or local file paths. All providers accept local paths — they are automatically handled.

Mode 8: ComfyUI Workflows

1. comfyui_workflow action="list"           -> See saved workflows
2. comfyui_workflow action="view" name="txt2img"  -> See adjustable parameters
3. comfyui_workflow action="modify" name="txt2img" modifications={"steps": 30}
4. generate_image prompt="..." workflow="txt2img"  -> Generate

Alternative Providers

You can use your own OpenAI-compatible API or a local ComfyUI instance instead of — or alongside — the default MeiGen provider. See references/providers.md for detailed configuration, model pricing, and provider comparison.
