Kalshi MCP access by plan
Your Kalshi MCP plan decides which tools the server runs. Every new account starts on Free.

- Basic
- Adds your Kalshi account — view your portfolio and place orders with your own API keys — plus a monthly call allotment and a longer history window. Starts with a 7-day free trial.
- Pro
- Adds order groups, the realized-gains CSV export, and far higher limits across calls, research, and trading.

Exact allotments, history windows, and prices are on the pricing page.
Add your Kalshi API keys
Portfolio and trading run on the paid plans. Add your Kalshi API Key ID and private key in the dashboard — a read-only key covers portfolio tools, a trading key covers orders. ChatGPT asks you to confirm each order tool call before it runs. Credentials are encrypted and never pass through ChatGPT.
ChatGPT access
ChatGPT applies its own gate: Developer mode decides whether a plugin can use MCP tools at all, independent of your Kalshi MCP plan above.
- Plus and Pro
- Developer mode is available on the web and gives the plugin read and write tools. Write actions such as placing an order ask for your confirmation in the chat before they run.
- Business, Enterprise, and Edu
- The same Developer mode, subject to workspace policy — an admin may need to allow it before it appears in Settings.
Plugins run on ChatGPT web.
