Gemini CLI
gemini extensions install https://github.com/predictionmarketspicks/mcp
In the Gemini web app (personal Google account, 18+, US, English, Keep Activity on): Settings → Connected Apps → Add a custom app, paste https://predictionmarketspicks.com/api/mcp/mcp?via=site-gemini, accept Google’s notice and click Connect. Developers can use gemini.google.com/devmode → Create new instead. Then name the app and the tool in your question — “Call the PredictionMarketsPicks fed_rate_odds tool: what are the odds the Fed cuts?” — because Gemini answers plain questions from web search.
Transcript
In a terminal, one command installs the PredictionMarketsPicks extension for Gemini CLI: gemini extensions install https://github.com/predictionmarketspicks/mcp. Running gemini mcp list shows the predictionmarketspicks server connected. Then a question in plain English, "Which Kalshi 15-minute markets are open right now?", makes Gemini call the fifteen_min_board tool and list every Kalshi 15-minute series with a window open, its YES price, close time, what it settles on and how often it settled up over the last 96 windows. In interactive mode Gemini asks you to approve the tool call; the demo uses -p with auto-approve to keep it short. No API key needed for the connector.

Gemini and prediction markets — frequently asked
What does the Gemini CLI extension install?
A small manifest and a context file from github.com/predictionmarketspicks/mcp. The extension itself runs no code on your machine — it points Gemini CLI at our hosted MCP server, which does the work and returns market data.
How do I update or remove the extension?
gemini extensions update predictionmarketspicks pulls the latest release; gemini extensions uninstall predictionmarketspicks removes it. Neither touches any other extension or setting.
Can Gemini see Kalshi prices without the extension?
Not live ones. Gemini can search the web, but a search result is a page snapshot, not the order book. The extension lets Gemini ask our tools for the price at the moment you ask.
Does this work in the Gemini web app, or only in Gemini CLI?
Both. In the Gemini web app (personal account, 18+, US, English, Keep Activity on): Settings → Connected Apps → Add a custom app, paste https://predictionmarketspicks.com/api/mcp/mcp?via=site-gemini, accept Google’s notice and Connect. Name PredictionMarketsPicks and the tool in your question, since Gemini answers plain questions from web search. In Gemini CLI the extension installs and gemini mcp list reads Connected. Same server either way, and 38 of the 45 tools answer with no key.
