Delegate routine work to agents
Describe a task in a short prompt. Agent Builder makes a plan and takes action, working across the apps your team uses daily. Turn any chat into an agent with one click to automate the task going forward.

Improve agents with feedback
Agents get better through use. Extend, modify, and refine your agents by giving them feedback like you would to a teammate. Agent Builder uses memory to incorporate corrections and deliver reliably good results.

Require approval for sensitive actions
Keep humans in the loop where it matters. Set tool-level approval requirements so agents check with you before executing sensitive steps. Review, edit, and approve actions with a centralized agent inbox.

Connect your tools securely
Enable first-party integrations, with OAuth for user authentication, and extend agent capabilities with any remote MCP server. Admins control which tools are available.
