What is the Mailsac MCP Server?
Connect your Mailsac account to any AI agent to automate your email testing and inbox management. This MCP server enables your agent to reserve private email addresses, retrieve and search for messages, and inspect HTML or plain text bodies directly from natural language interfaces.
What you can do
- Inbox Oversight — List and manage your reserved (enhanced) addresses and custom domains
- Instant Retrieval — Fetch a list of messages received by any address in your account instantly
- Content Extraction — Retrieve sanitized HTML or raw plain text bodies to extract verification codes or links
- Inbox Maintenance — Permanently delete individual messages or clear entire inboxes via simple commands
- Infrastructure Management — Reserve new private addresses programmatically for isolated testing flows
- Global Search — Query messages across all your addresses using advanced search parameters (requires paid tier)
How it works
1. Subscribe to this server
2. Enter your Mailsac API Key

Frequently asked questions
What is an 'Enhanced' address in Mailsac?
An enhanced address is a private inbox that only you can access. Use the reserve_new_address tool to make an address private/enhanced.
Can I read the raw SMTP source of an email?
While this server provides tools for HTML and Plain Text bodies, the Mailsac API supports raw data retrieval. You can use the text body tool to extract key technical metadata.
Is an API Key required for all addresses?
Yes, this MCP server requires an API Key to interact with your account and access your reserved resources and private messages.
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 Mailsac 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.
