Research direction

Start with SEP-1319 and the linked specification changes, then trace the PHP SDK's request payload and RPC method definitions. Done means the payload definitions are independent and the RPC method definitions refer to them consistently across the SDK.

Description

Schema

Issue to address and track SEP-1319:

This SEP proposes a structural refactoring of the Model Context Protocol (MCP) specification. The core change is to define payload of requests (e.g., CallToolRequest) as independent definitions and have the RPC method definitions refer to these models. This decouples the definition of the data payload from the definition of the remote procedure that transports it, leading to a clearer, more modular, and more maintainable specification.
