Struct Bus 

pub struct Bus {
    pub db: PgPool,
    pub hub: EventHub,
    pub tool_router: ToolRouter<Self>,
}

The MCP server. Cheap to clone: PgPool and EventHub are Arcs internally, and the tool router is rebuilt per session by the transport’s service factory.

Fields

db: PgPool

hub: EventHub

tool_router: ToolRouter<Self>
