In depth
The default communication method between MCP clients and servers. The client spawns the server as a child process and sends JSON-RPC messages over stdin/stdout. Stdio transport requires no network configuration, works entirely locally, and is the simplest way to connect an MCP server. It is used by Claude Code, Cursor, and most MCP clients for local development workflows.
