JSON-RPC 2.0
Core Facts
MCP采用客户端-服务器架构，基于标准化的JSON-RPC通信协议
Anthropic officially released the MCP specification at the end of 2024, adopting JSON-RPC 2.0 as the underlying communication protocol.
MCP基于JSON-RPC 2.0协议构建，支持请求-响应和通知两种消息模式
Timeline (last 90 days)
Capability discovery requests, tool calls, and status reports all circulate within the closed loop in JSON-RPC 2.0 message format.
A2A is an HTTP-based open protocol that uses JSON-RPC 2.0 as its message format.
LSP builds a stateful, asynchronous client-server communication model on top of JSON-RPC 2.0, involving phases such as initialization, document synchronization, actual requests, and shutdown.
In stdio transport mode, the client writes JSON-RPC requests to the server process via stdin and reads responses via stdout, enabling local inter-process communication without requiring an HTTP port.
LSP基于JSON-RPC 2.0协议进行通信，核心消息类型包括textDocument/completion、textDocument/definition、textDocument/diagnostic等
LSP communicates based on the JSON-RPC 2.0 protocol and has currently evolved to version 3.17.
JSON-RPC 2.0标准请求消息包含四个字段：jsonrpc、method、params、id，响应消息包含result或error
