A Rust-based MCP (Model Context Protocol) server that lets users send emails by writing natural-language prompts in LLM chat interfaces such as Cursor and Copilot. It uses the official MCP Rust SDK and the lettre crate as an SMTP client.
For local testing, run a Python SMTP server (python -m aiosmtpd -n -l 127.0.0.1:2525), configure the MCP agent in VSCode, start the agent, then run cargo run. Prompts like “send a formal email to Bob (bob@domain.com)…” are then processed by the LLM.
lettre crate)Python 3 with the `aiosmtpd` module for the SMTP server, Visual Studio Code with GitHub Copilot, and Rust for building the MCP server.
Traditional programs require manual data input; this server lets the LLM interpret natural-language prompts and construct the email automatically.
It uses SMTP, implemented by the `lettre` crate.
Not yet. The README lists “add recipient management” and “support more request types, e.g. schedule meetings” as future TODO items.
The README does not specify any authentication or encryption; the local test example uses plain SMTP on `127.0.0.1:2525`.
