MCP Image Recognition Server
LocalAbout MCP Image Recognition Server
MCP Image Recognition Server is an MCP server that describes images using Anthropic Claude Vision or OpenAI vision models. It suits users who need image understanding in MCP clients, with primary and fallback provider settings and optional Tesseract OCR text extraction.
Key features
- 01Image descriptions from Anthropic or OpenAI vision models
- 02Configurable primary and fallback providers
- 03Base64 and file-path image input
- 04Optional Tesseract OCR text extraction
Use cases
- 01Adding image content descriptions to MCP client workflows
- 02Extracting text from images alongside descriptions
- 03Using OpenRouter to access other vision models
MCP support
This is an MCP server that exposes the describe_image and describe_image_from_file tools, returning detailed descriptions of images to MCP clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details

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
- Clone the repository:
git clone https://github.com/mario-andreschak/mcp-image-recognition.git
cd mcp-image-recognition
- Create and configure your environment file:
cp .env.example .env

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
-
describe_image- Input: Base64-encoded image data and MIME type
- Output: Detailed description of the image
-
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 (anthropicoropenai).FALLBACK_PROVIDER: Optional fallback provider.LOG_LEVEL: Logging level (DEBUG, INFO, WARNING, ERROR).ENABLE_OCR: Enable Tesseract OCR text extraction (trueorfalse).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 tohttps://openrouter.ai/api/v1for 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:
- Obtain an OpenAI API key from OpenRouter.
- Set
OPENAI_API_KEYin your.envfile to your OpenRouter API key. - Set
OPENAI_BASE_URLtohttps://openrouter.ai/api/v1. - Set
OPENAI_MODELto the desired model using the OpenRouter format (e.g.,anthropic/claude-3.5-sonnet:beta). - Set
VISION_PROVIDERtoopenai.
Default Models
- Anthropic:
claude-3.5-sonnet-beta - OpenAI:
gpt-4o-mini - OpenRouter: Use the
anthropic/claude-3.5-sonnet:betaformat inOPENAI_MODEL.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
