Features
--------

[](#features)

- **JSON-RPC 2.0 engine** with full batch support
- **Three MCP primitives**: Tools, Resources, and Prompts

- **Two transports**: Stdio (local AI tools) and Streamable HTTP (remote)
- **PSR-15 Middleware**: Drop-in HTTP integration for any PSR-15 framework
- **DI Provider**: Bootstrap the full MCP stack from MLC configuration
- **MCP Client**: HTTP and Stdio clients for connecting to external MCP servers
- **Schema generation** from PHP method signatures via reflection
- **Schema validation** for tool arguments (types, enums, ranges)
- **Protocol negotiation**: `2024-11-05` and `2025-03-26`
- **Session management** via `MCP-Session-Id` header
