thumbnail-mcp

# Thumbnail MCP Tool A Replicate-based tool for generating thumbnail images via the MCP protocol. ## Setup 1. Make sure you have a Replicate API key 2. Set the environment variable `REPLICATE_API_KEY` with your key 3. Install dependencies: ``` composer install ``` ## Testing the Tool ### Method 1: Using the Mock Test This method uses a mocked platform to test the tool structure without making real API calls: ```bash php test_thumbnail.php ``` ### Method 2: Using the Real API This method makes actual API calls to Replicate: ```bash REPLICATE_API_KEY=your_api_key php test_real.php ``` ### Method 3: Using the Symfony Command This is the most realistic test as it uses the Symfony DI container: ```bash # Make sure you have the API key in .env.local bin/console app:test-thumbnail "Your Name" ``` ## Tool Usage in MCP The tool is registered via the `AsTool` attribute and will be available in the MCP toolbox with the name `mcp_thumbnail`. It takes a single string parameter `name` that will be used in the prompt. Example usage: ```json { "name": "John Doe" } ``` The tool will return a string with the URL of the generated thumbnail image.
