Integrates with Mailtrap Email API.
Mailtrap mcp server connects Mailtrap to AI assistants that speak the Model Context Protocol. Integrates with Mailtrap Email API.
An MCP server that provides tools for sending and testing in sandbox via Mailtrap.
The server is distributed via npm as @smithery/cli, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Before the server will start you need to supply 8 environment variables: MAILTRAP_API_TOKEN, DEFAULT_FROM_EMAIL, MAILTRAP_ACCOUNT_ID, MAILTRAP_TEST_INBOX_ID, ASDF_DIR, ASDF_DATA_DIR, ASDF_NODEJS_VERSION, MAILTRAP_SANDBOX_ID. Keep credentials in your client's env block or a secrets manager rather than committing them.
Before using this MCP server, you need to: 1. Create a Mailtrap account 2. Verify your domain 3. Get your API token from Mailtrap API settings 4. Get your Account ID from Mailtrap account management Required Environment Variables: -
Communication servers earn their keep on volume — summarising channels and threads that would otherwise cost you an hour of scrollback. Mailtrap sits in that group. Worth comparing against the other communication servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
