Overview

This project provides an API to access the Unsplash service, allowing you to search, list, and get random images. Additionally, it integrates the Model Context Protocol (MCP), enabling AI models like Claude to interact directly with the Unsplash API.

FastAPI-MCP FastAPI

Prerequisites

Before using the Unsplash API, you need to:

1. Register as a developer on Unsplash
2. Obtain your Access Key
3. Configure the key as UNSPLASH_CLIENT_ID in the .env file

Installation

Using pip

# Clone the repository
git clone https://github.com/your-username/unsplash-api-mcp.git
cd unsplash-api-mcp

# Install dependencies
pip install -r requirements.txt

# Configure environment variables
cp .env.example .env
# Edit the .env file and add your UNSPLASH_CLIENT_ID

Using Docker

# Clone the repository
git clone https://github.com/your-username/unsplash-api-mcp.git
cd unsplash-api-mcp

# Configure environment variables
cp .env.example .env
# Edit the .env file and add your UNSPLASH_CLIENT_ID

# Build and start the container
docker compose up -d

Configuration

Create a .env file in the project root with the following content:

UNSPLASH_CLIENT_ID=your_access_key_here

Running

Locally

python main.py

The API will be available at http://localhost:8000.

With Docker

docker compose up -d

The API will be available at http://localhost:8000.

Access the interactive API documentation at http://localhost:8000/docs.

API Endpoints

Search

Endpoint to search for images on Unsplash.

MCP Integration

MCP Overview

The Model Context Protocol (MCP) is a protocol that allows AI models to interact directly with APIs and services. This implementation uses FastAPI-MCP to expose the Unsplash API endpoints as MCP tools.

MCP Endpoints

The MCP server is available at /mcp and exposes all API endpoints as MCP tools:

• search: Search for images on Unsplash
• photos: List photos from the landing page
• random: Get random photos

Using with AI Models

AI models that support MCP can connect to this API using:

http://your-server:8000/mcp

For Claude, you can configure the connection in the model settings or via API.

Example Client

You can test the MCP server with a simple Python client:

import requests

def test_mcp_metadata():
    """Test if the MCP server is working correctly."""
    response = requests.get("http://localhost:8000/mcp/.well-known/mcp-metadata")
    if response.status_code == 200:
        print("MCP server working correctly!")
        print(f"Response: {response.json()}")
    else:
        print(f"Error: {response.text}")

def list_mcp_tools():
    """List the available tools in the MCP server."""
    response = requests.post(
        "http://localhost:8000/mcp/jsonrpc",
        json={
            "jsonrpc": "2.0",
            "id": 1,
            "method": "mcp/list_tools"
        }
    )
    if response.status_code == 200:
        print("Available MCP tools:")
        for tool in response.json()["result"]["tools"]:
            print(f"- {tool['name']}: {tool['description']}")
    else:
        print(f"Error: {response.text}")

if __name__ == "__main__":
    test_mcp_metadata()
    list_mcp_tools()

For more information about using MCP, see the MCP_USAGE.md file.

Development

To contribute to development:

1. Clone the repository
2. Install development dependencies: pip install -r requirements.txt
3. Create a .env file with your Unsplash API key
4. Run the server in development mode: python main.py
