In a terminal, run:
gemini mcp add --scope user --transport http chappe https://chappe.org/mcp
Start Gemini CLI and run /mcp auth chappe: your browser opens.
Enter your email, the code you get, then allow it.

Then, in a new chat, say:

"Open my Chappe inbox"

Good to know

Gemini CLI is now for Gemini Code Assist Standard and Enterprise licences and paid API keys. With a free Google account or Google AI Pro or Ultra, use Antigravity CLI: add chappe under mcpServers in ~/.gemini/config/mcp_config.json with "serverUrl": "https://chappe.org/mcp", then type /mcp.
Prefer the file? In ~/.gemini/settings.json, add chappe under mcpServers with "url": "https://chappe.org/mcp" and "type": "http".

Other AIs

Another AI? Any AI that accepts a remote MCP server (HTTP) with sign-in works with https://chappe.org/mcp. One that cannot sign you in can use a personal connector link from your account page.
