Yes. The Gemini CLI supports MCP servers through the gemini mcp add command, the same way Claude Code does, so the local Hostfully MCP server you build works with Gemini with no changes. Point it at the same index.js and ask Gemini about your properties, leads, orders, and guests.
What works today
The Gemini CLI reads MCP servers from ~/.gemini/settings.json and supports both local (stdio) and remote (HTTP) servers. Because the Hostfully server in our guide runs locally over stdio, it drops straight into Gemini's config, no hosting or rewriting required.
As with Claude, the server is read-only by default, so Gemini can read your Hostfully data but cannot change anything, and your API key and agency UID stay in environment variables on your own machine.
The hosted API route
If you would rather build a tool against the Hostfully API than run and maintain a server, our Hostfully API guide covers how access works and the limits worth planning around before you write any code.
