Frequently asked questions
Can I both test and send emails with Mailtrap?
Yes. Mailtrap supports both Email Testing (capturing emails in staging) and Email Sending (transactional delivery in production).
Does Mailtrap require an Account ID?
Yes. You need both an API Key and Account ID to authenticate via Bearer token against mailtrap.io/api.
Can I analyze spam scores and HTML rendering?
Yes. Mailtrap analyzes captured emails for spam score (SpamAssassin), blacklists, HTML errors, and client support.
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 Mailtrap 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.
