//! Model Context Protocol — both directions.
//!
//! - [`client`] — connect to external MCP servers (stdio / HTTP / SSE), discover
//! their tools, and register them into the Aonyx [`ToolRegistry`](aonyx_tools::ToolRegistry).
//! - [`server`] — expose Aonyx's own tool catalogue + memory tools to other
//! agents (Claude Code, Cursor, Cline, …).
