FastestMCP.RequestContext (fastest_mcp v0.1.2)

Immutable snapshot of request metadata exposed through FastestMCP.Context.

FastestMCP.Context remains the main runtime object passed to handlers. FastestMCP.RequestContext exists for the narrower case where you want a stable, serializable summary of the current request without depending on the full context struct.

The primary style stays explicit: handlers receive ctx, and advanced code can derive %FastestMCP.RequestContext{} from it when they need a smaller, stable request snapshot.

Example

FastestMCP.add_tool(server, "inspect_request", fn _arguments, ctx ->
  request = FastestMCP.Context.request_context(ctx)

  %{
    request_id: request.request_id,
    transport: request.transport,
    path: request.path
  }
end)
