API and MCP server in Rust; a public index at the API root1//! The public API: REST at api.g1t.sh and the MCP server at mcp.g1t.sh.
2//!
3//! One Worker, two hostnames. Both are thin adapters over the same
4//! operations (see [`operations::Op`]), which call the services that own
5//! the data. This Worker holds none.
