A backend is an agent server and the workspace it operates in. A workspace is the folder, mounted project directory, container, or cloud sandbox where the agent reads and writes files. All conversations, settings, and automations run against whichever backend is currently selected.

Connecting to a Backend

Any Agent Canvas frontend can connect to any Agent Canvas backend. Use the backend switcher in the UI to open Manage Backends, where you can add, edit, or remove entries. Each entry stores a display name, host URL, and an API key for authentication. Settings, LLM configuration, MCP servers, and automations are all scoped to the active backend — switching backends switches all of these.
