Gemma runs on your own hardware with Ollama or LM Studio. Ollama alone does not connect to MCP servers: go through an interface. The most common is Open WebUI (version 0.6.31 or later, administrator account):
- In your Mailpro account, on the AI Assistants (MCP) page, copy the server address.
- In Open WebUI, open Settings › Admin › Integrations, then under External Tool Servers click + Add Connection.
- Type: MCP (Streamable HTTP). Paste the address into Server URL.
- Auth: OAuth 2.1, then click Register Client and Save.
- In a conversation, choose your Gemma model, then + › Tools and turn on Mailpro: the Mailpro sign-in page opens the first time.
- In Mailpro, on the AI Assistants page, set how it sends: with approval or direct, within a daily cap you set.
Recommended model: Gemma 4. A model that is too small handles tool calling poorly.
For LM Studio or LibreChat, and to set WEBUI_SECRET_KEY: the self-hosted AI guide. All about Gemma: Gemma and Mailpro.
