# MCP Image Placeholder Server

This is a Model Context Protocol (MCP) server that provides a tool for generating placeholder images from different providers.

## Features

- Generates placeholder images from supported providers
- Supports two image providers:
  - [`placehold`](https://placehold.co/): Provides simple placeholder images
  - [`lorem-picsum`](https://picsum.photos/): Provides real images as placeholder images
- Validates input parameters
- Returns image URLs for immediate use

## Requirements

- Python 3.9+
- `uv` package manager

## Installation

1. Clone this repository
2. [Set up the configuration for MCP server](#configuration)

## Usage

The server exposes one tool:

### `image_placeholder`

Generate a placeholder image URL based on specified parameters.

**Parameters:**
- `provider`: The image provider to use (`placehold` or `lorem-picsum`)
- `width`: The width of the image (1-10000)
- `height`: The height of the image (1-10000)

**Returns:**
- URL string of the generated image

**Example Usage:**
```python
# Generate a 300x200 placeholder image
url = image_placeholder(provider="placehold", width=300, height=200)

# Generate a 500px square lorem-picsum image
url = image_placeholder(provider="lorem-picsum", width=500)
```

               "command": "uv",
               "args": [
                   "--directory",
                   "/ABSOLUTE/PATH/TO/PROJECT",
                   "run",
                   "main.py"
               ]
           }
       }
   }
   ```
