RMCP Mailer
by alvinhon
Rust-based MCP server for sending emails and managing templates via LLM prompts.
What it does
RMCP Mailer enables AI agents to send emails through an SMTP client. Instead of manual data entry, you can use natural language to draft formal emails, invite guests, or manage email templates, which the LLM then converts into formatted emails sent via the lettre crate.
Tools
send_email: Sends a formal or informal email to a specified recipient.create_template: Saves an email template for future reuse.send_template_email: Sends an email using a previously defined template.
