FAQ

Frequently asked questions

01

Can I send a physical letter using my AI agent?

Yes! Use the create_physical_letter action. Provide the recipient details and a template ID to trigger printing and mailing programmatically.

02

How does AutoGen connect to MCP servers?

Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Stannp tools during their conversation turns.

03

Can different agents have different MCP tool access?

Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.

04

Does AutoGen support human approval for tool calls?

Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
