Connect LibreChat to your emails

Why connect LibreChat to your emails?

LibreChat is the leading open-source alternative to ChatGPT, giving you full control over your AI stack. You self-host it, choose your models and own your data. But until now, connecting it to your email has required custom development or third-party services that compromise your privacy.

MailMCP brings native email capabilities to LibreChat. Once connected, your AI models can read your inbox, search for specific messages, draft and send replies, schedule emails, manage folders and organize conversations. All through the same chat interface, with the model of your choice — Claude, GPT-4, Mistral, Llama or any other compatible LLM.

Integration is straightforward: add a few lines to your librechat.yaml file with your MailMCP credentials, restart the application, and the email tools become available to all compatible models. No external dependency, no complex configuration.

Frequently asked questions

Does LibreChat support MCP?

Can I use MailMCP with OpenWebUI?

MailMCP is compatible with any platform that supports the MCP protocol. If OpenWebUI adds MCP support, you will be able to connect MailMCP in the same way. Currently, LibreChat is the recommended open-source chat interface for using MailMCP with self-hosted AI models.

Is LibreChat email integration self-hosted?

LibreChat runs on your own server, and MailMCP provides the email bridge as a hosted service. Your emails are never stored by MailMCP — it acts as a secure proxy. This gives you the privacy benefits of self-hosted AI while adding reliable email connectivity through the MCP standard.
