# MooseCP Image Server
|
||
|
||
A Model Context Protocol (MCP) server designed to provide LLMs with efficient, token-optimized visual access to image directories and AI generation capabilities. Instead of dumping full-resolution images (which waste tokens and cause context overflow), MooseCP provides a hierarchical workflow: **List $\rightarrow$ Scan $\rightarrow$ Preview $\rightarrow$ Inspect**.
|
||
|
||
## ⚠️ AI SLOP DISCLAIMER
|
||
This entire project was vibe-coded by an AI. It is 100% slop code. Use it at your own risk.
|
||
|
||
## 🚨 SECURITY WARNING
|
||
**This server is designed to be run on `localhost` ONLY.**
|
||
It contains tools (such as `read_image` and `list_directory`) that allow the LLM to read arbitrary files from your filesystem. If you expose this server to the network or a public IP, any user or compromised AI could potentially read sensitive system files (e.g., SSH keys, `/etc/passwd`).
|
||
**NEVER run this server on a public-facing IP without implementing strict path validation.**
|
||
|
||
## Tools Overview
|
||
|
||
### 📁 `list_directory`
|
||
Provides a simplified file-browser view of a directory.
|
||
* **Best for**: Getting a sense of the files present and their basic metadata (size, date).
|
||
* **Features**: Pagination and sorting by name, size, or modification date.
|
||
|
||
### 🖼️ `contact_sheet`
|
||
Generates a high-density grid of thumbnails.
|
||
* **Best for**: Quickly scanning hundreds of images to find a specific one or get a general "vibe" of a folder.
|
||
* **Note**: This tool is paginated. You must iterate through pages to see all images in a folder.
|
||
* **Workflow**: Use the indices shown on the contact sheet to call `preview_image`.
|
||
|
||
### 🔍 `preview_image`
|
||
Provides medium-detail previews optimized for the model's token budget.
|
||
* **Best for**: Comparing a few candidates, inspecting specific details, or selecting a "favorite" image.
|
||
* **Efficiency**: Automatically calculates dimensions to fit the model's patch size (e.g., 48px patches for Gemma 4), ensuring maximum detail without wasting tokens on padding.
|
||
* **Workflow**: Pass indices from the `contact_sheet` or a direct file path.
|
||
|
||
### 📖 `read_png_metadata`
|
||
Extracts AI generation parameters from PNG files.
|
||
* **Best for**: Retrieving prompts, seeds, and model hashes from AI-generated images.
|
||
|
||
### 📸 `read_image`
|
||
Returns the full-resolution image.
|
||
* **Best for**: Final confirmation or deep visual analysis where every pixel counts.
|
||
|
||
### 🎨 `generate_image`
|
||
Triggers an image generation on a local Stable Diffusion WebUI Forge instance.
|
||
* **Workflow**: Always call `get_model_info` first to determine the correct prompting style (e.g., tag-based vs. natural language).
|
||
* **Features**: Supports model-specific presets, resolution presets, and standard parameter overrides.
|
||
* **Output**: Returns a Base64 image for AI analysis and a proxy URL for direct embedding in the chat.
|
||
|
||
### ℹ️ `get_model_info`
|
||
Provides the "manual" for available generation models.
|
||
* **Best for**: Learning the prompting style, recommended settings, and available resolution presets for a specific model.
|
||
* **Workflow**: Call without arguments to see the catalog; call with `model_name` for the detailed guide.
|
||
|
||
### 🏷️ `search_tags`
|
||
Searches the Danbooru tag database for recognized tags and aliases.
|
||
* **Best for**: Finding the correct booru-style tags, checking tag popularity, and resolving aliases (e.g., 'lesbian' → 'yuri').
|
||
* **Workflow**: Provide a query string to get a list of the most popular matching tags.
|
||
|
||
### 🌐 `browse_wikipedia`
|
||
Allows the model to browse Wikipedia using its API.
|
||
* **Best for**: Quickly retrieving summaries, structural maps (ToC), or specific section content from Wikipedia without dumping the entire page.
|
||
* **Workflow**: Use `mode='summary'` (default) to get an overview and a Table of Contents. Use `mode='section'` with a linear index from the ToC to dive into specific details.
|
||
* **Features**: Returns raw Wikitext to save tokens, handles redirects, and automatically falls back to a search result list if a page is not found.

## Installation & Requirements
|
||
|
||
### Dependencies
|
||
This server requires Python 3.10+ and the following packages:
|
||
* `uvicorn`: ASGI server for the SSE transport.
|
||
* `starlette`: Lightweight ASGI framework.
|
||
* `Pillow`: Image processing and thumbnail generation.
|
||
* `requests`: For communicating with the Stable Diffusion API.
|
||
* `httpx`: For asynchronous API requests (e.g., Wikipedia).
|
||
|
||
```bash
|
||
pip install -r requirements.txt

### Setup
|
||
1. Clone this repository to your server.
|
