Mail MCP Server

How to use

You connect your MCP-enabled client to the Mail MCP Server and start issuing natural language instructions. You can perform common email tasks such as listing folders, viewing the latest messages, sending messages, performing searches, and handling attachments. The server translates your requests into email client actions and returns human-friendly results that you can present to the user.

How to install

Prerequisites you need before installation are Node.js and npm, and Python 3.11 or newer if you plan to use the bridging script locally.

Install Smithery to enable automatic installation of Mail MCP Tool for your desired client.

Clone the project, install dependencies, and build the project locally.

Configure the MCP client to connect to the Mail MCP Server using a local stdio bridge and the required environment settings.

Start the client, restart the editor or runner if needed, and begin issuing email-related commands.

Additional sections

Notes on configuration and usage follow in the next sections. You will configure a local bridge so the MCP client talks to your email service via the bridging script. The following environment variables are used to connect to your SMTP/IMAP servers and to set the default sender information. Ensure you provide valid credentials and adjust hostnames and ports to match your email provider.

Configuration and security

All email operations are performed locally by the bridge script. No sensitive data is sent to external servers beyond your own email provider. Keep your credentials secure and avoid sharing your bridge configuration. Use strong application-specific passwords when required by your email service.
