MCP server for image recognition using Anthropic and OpenAI vision APIs

MCP Image Recognition Server

An MCP server that provides image recognition capabilities using Anthropic and OpenAI vision APIs. Version 0.1.2.

Features

• Image description using Anthropic Claude Vision or OpenAI GPT-4 Vision
• Support for multiple image formats (JPEG, PNG, GIF, WebP)
• Configurable primary and fallback providers
• Base64 and file-based image input support
• Optional text extraction using Tesseract OCR

Requirements

• Python 3.8 or higher
• Tesseract OCR (optional) - Required for text extraction feature
  • Windows: Download and install from UB-Mannheim/tesseract
  • Linux: sudo apt-get install tesseract-ocr
  • macOS: brew install tesseract

Installation

1. Clone the repository:

git clone https://github.com/mario-andreschak/mcp-image-recognition.git
cd mcp-image-recognition

2. Create and configure your environment file:

cp .env.example .env
# Edit .env with your API keys and preferences

3. Build the project:

build.bat

Usage

Running the Server

Spawn the server using python:

python -m image_recognition_server.server

Start the server using batch instead:

run.bat server

Start the server in development mode with the MCP Inspector:

run.bat debug

Available Tools

1. describe_image

   • Input: Base64-encoded image data and MIME type
   • Output: Detailed description of the image

2. describe_image_from_file

   • Input: Path to an image file
   • Output: Detailed description of the image

Environment Configuration

• ANTHROPIC_API_KEY: Your Anthropic API key.
• OPENAI_API_KEY: Your OpenAI API key.
• VISION_PROVIDER: Primary vision provider (anthropic or openai).
• FALLBACK_PROVIDER: Optional fallback provider.
• LOG_LEVEL: Logging level (DEBUG, INFO, WARNING, ERROR).
• MAX_TOKENS: Maximum number of tokens generated in a vision response (default: 1024).
• ENABLE_OCR: Enable Tesseract OCR text extraction (true or false).
• TESSERACT_CMD: Optional custom path to Tesseract executable.
• OPENAI_MODEL: OpenAI Model (default: gpt-4o-mini). Can use OpenRouter format for other models (e.g., anthropic/claude-3.5-sonnet:beta).
• OPENAI_BASE_URL: Optional custom base URL for the OpenAI API. Set to https://openrouter.ai/api/v1 for OpenRouter.
• OPENAI_TIMEOUT: Optional custom timeout (in seconds) for the OpenAI API.

Using OpenRouter

OpenRouter allows you to access various models using the OpenAI API format. To use OpenRouter, follow these steps:

1. Obtain an OpenAI API key from OpenRouter.
2. Set OPENAI_API_KEY in your .env file to your OpenRouter API key.
3. Set OPENAI_BASE_URL to https://openrouter.ai/api/v1.
4. Set OPENAI_MODEL to the desired model using the OpenRouter format (e.g., anthropic/claude-3.5-sonnet:beta).
5. Set VISION_PROVIDER to openai.

Default Models

• Anthropic: claude-3.5-sonnet-beta
• OpenAI: gpt-4o-mini
• OpenRouter: Use the anthropic/claude-3.5-sonnet:beta format in OPENAI_MODEL.
