You're all done! Upon completing this setup, your project will include 3 new API endpoints:
- Streaming Endpoint for MCP Clients: GET /{default_path}/sse
- Request Submission Endpoint: POST /{default_path}/messages
- Streamable HTTP Endpoint: GET|POST /{default_path}
The project includes a Docker setup that can be used for development. The Docker setup includes Nginx, PHP-FPM with Redis extension, and Redis server.
For detailed instructions on how to set up and use the Docker containers, please refer to the Development Guidelines.

Create powerful tools that AI agents can orchestrate:
- StreamableToolInterface: Real-time progress updates for long-running operations
- Multi-Result Support: Return text, images, audio, or resources
- Progress Notifications: Keep users informed during complex agent operations
- Dynamic Tool Discovery: Agents can discover and use tools based on capabilities
php bin/console make:mcp-tool MyCustomTool
php bin/console mcp:test-tool MyCustomTool --input='{"task":"analyze this code"}'
```
- MCP Inspector: Visualize and debug agent behavior
- Test Commands: Rapid agent development and testing
