Frequently asked questions
How do I find my Server ID?
Use the list_virtual_servers tool to see a comprehensive list of all servers in your account along with their unique IDs.
Can I search for messages by recipient email?
Yes, use the search_server_messages tool and provide a JSON criteria object with the sentTo field.
Does Mailosaur support SMS messages?
Absolutely. Mailosaur treats SMS messages similarly to emails. You can list and search for them within your virtual servers just like email content.
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 Mailosaur tools during their conversation turns.
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.
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.
