Connect Gemini CLI to Quest Portal

Add Quest Portal to Google's Gemini CLI with one command.

The address to use: https://mcp.questportal.com/mcp

Steps from the vendor's documentation. Menu names change, so if a step doesn't match what you see, look for the closest option or check Google's documentation: https://geminicli.com/docs/tools/mcp-server/

What you need

  • A Quest Portal account with Core or Pro, including the free trials. With Core your assistant can read your campaigns; with Pro it can also make changes.

  • Gemini CLI installed.

Set up

Step 1: Add the server. In a terminal, run:

Step 2: Sign in. Start Gemini CLI and run:

Step 3: Approve access in Quest Portal. A Quest Portal page opens in your browser. Sign in if asked, check what Gemini CLI is asking to use, and click Allow access.

Good to know

  • Check the connection with /mcp. Remove it with gemini mcp remove questportal.

  • Sign-in needs a browser on the same machine.

  • Google replaced Gemini CLI with Antigravity CLI for unpaid and Google One accounts in June 2026. We haven't confirmed Quest Portal in Antigravity yet.

More fun at the table, less fuss around it

The tavern falls quiet. You spent all week on this villain: the scarred voice, the secret letter, the slow reveal in the final act. Your players have other plans. They have just set fire to the only bridge out of town, the paladin is deep in an argument with a goat, and the rogue has quietly pocketed the letter that was supposed to unravel everything. Somewhere across the river, your villain stands alone in the rain, waiting for an entrance that will never come. The bard leans back, grinning. Four faces turn to you.
