# MCP Bundle [WIP] > [!IMPORTANT] > **PHP LLM becomes Symfony AI** - this project moved to [github.com/symfony/ai](https://github.com/symfony/ai). > Please use the new repository for all future development, issues, and contributions. > Thanks for your contributions - we hope to see you at Symfony AI! Symfony integration bundle for [Model Context Protocol](https://modelcontextprotocol.io/) using the unofficial PHP SDK [php-llm/mcp-sdk](https://github.com/php-llm/mcp-sdk) library. **Currently only supports tools as server via Server-Sent Events (SSE) and STDIO.** ## Installation ```bash composer require php-llm/mcp-bundle ``` ## Usage At first, you need to decide whether your application should act as a MCP server or client. Both can be configured in the `mcp` section of your `config/packages/mcp.yaml` file. ### Act as Server **Currently only supports tools.** To use your application as an MCP server, exposing tools to clients like [Claude Desktop](https://claude.ai/download), you need to configure in the `client_transports` section the transports you want to expose to clients. You can use either STDIO or SSE. ### Act as Client **Not implemented yet.** To use your application as an MCP client, integrating other MCP servers, you need to configure the `servers` you want to connect to. You can use either STDIO or Server-Sent Events (SSE) as transport methods. You can find a list of example Servers in the [MCP Server List](https://modelcontextprotocol.io/examples). Tools of those servers are available in your [LLM Chain Bundle](https://github.com/php-llm/llm-chain-bundle) configuration and usable in your chains. ## Configuration ```yaml mcp: app: 'app' # Application name to be exposed to clients version: '1.0.0' # Application version to be exposed to clients # Configure this application to act as an MCP server # Currently exposes tools registered in LLM Chain client_transports: stdio: true # Enable STDIO via command sse: true # Enable Server-Sent Event via controller # Configure MCP servers to be used by this application # Not implemented yet servers: name: transport: 'stdio' # Transport method to use, either 'stdio' or 'sse' stdio: command: 'php /path/bin/console mcp' # Command to execute to start the client arguments: [] # Arguments to pass to the command sse: url: 'http://localhost:8000/sse' # URL to SSE endpoint of MCP server ```
