What is the Mailtrap MCP server?
Mailtrap is an MCP server listed in the public MCP registry as io.mailtrap/mcp. Official MCP Server for Mailtrap. This page covers its npm package (mcp-mailtrap).
Is the Mailtrap MCP server safe to use?
Mailtrap scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 29 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Mailtrap MCP server expose?
Mailtrap exposes 125 tools: send-email, batch-send-transactional-email, batch-send-bulk-email, create-template, list-templates, and 120 more. Their descriptions and schemas cost roughly 10,495 tokens of context every time the server is loaded.
Is the Mailtrap MCP server still maintained?
Mailtrap is still listed as active in the MCP registry. We last reached this channel on 29 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Mailtrap MCP server under?
Mailtrap declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
