1//! `McpServerConfig` impl for the unified config's `McpConfig` section.
2//!
3//! Type definitions live in `ferridriver-config`. This module wires those
4//! types into the runtime `McpServerConfig` trait so the MCP server can be
5//! driven directly from a `ferridriver.toml` file with no custom Rust code.
