Security Scan

The skill's requirements and instructions are coherent with an image-generation toolkit that delegates to a pinned npm package and local ComfyUI; it asks users to configure provider tokens or local endpoints but otherwise stays within expected scope.

Purpose & Capability

The name and description match the instructions: it routes image generation across providers, offers prompt enhancement, and manages local ComfyUI workflows. Requested binaries (mcporter, npx, node) are appropriate for running an MCP server via npx.

Instruction Scope

SKILL.md directs the agent and user to add an MCP server entry (runs `npx meigen@1.2.8`) and to read/write local config files (~/.config/mcporter/config.json, ~/.config/meigen/config.json, ~/.clawdbot/.env). This is expected for configuring providers, but the agent will cause execution of remote npm code and will read/write local config paths when the user configures a provider.

Install Mechanism

There is no packaged install; the skill relies on npx to fetch and run meigen@1.2.8 from npm at runtime. Using a pinned npm version is good practice, but npx/npm execution is a moderate-risk mechanism because it runs code fetched from the network.

Credentials

The registry declares no required env vars. The SKILL.md explains optional provider credentials (MEIGEN_API_TOKEN, openaiApiKey, comfyuiUrl) used only to enable generation—these are proportionate to the skill's purpose. It does instruct storing tokens in local config files (recommended chmod 600).

Persistence & Privilege

always:false and normal autonomous invocation settings. The skill instructs adding a persistent MCP server entry to mcporter config and storing provider tokens locally, which is expected for a provider-integrating tool and does not demand unusual platform privileges.

Assessment

This skill is internally consistent for multi-provider image generation, but it requires running a pinned npm package via npx and writing local config files. Before installing: (1) review the meigen npm package and its GitHub source (the SKILL.md links are provided) to ensure you trust the publisher; (2) prefer using a local ComfyUI endpoint if you want to avoid sending images/tokens to third parties; (3) only supply API tokens you trust and store them with restricted permissions (chmod 600); (4) be aware npx will fetch and execute code from the network—if you need higher assurance, fetch the package source, audit it, and run it in an isolated environment or container.

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@1.2.8"]
    }
  }
}

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 Nanobanana 2 or Seedream 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.
