Use Kalshi Eye in ChatGPT

ChatGPT can use Kalshi Eye as a custom MCP server: ask it about Kalshi, Polymarket and Limitless markets, how a market traded, what was recorded and which files hold it. You sign in with your Kalshi Eye account; there is no key to copy.

Updated November 13, 2026.

Add Kalshi Eye

  1. Go to chatgpt.com/plugins, press +, then Add custom MCP server.
  2. Name it Kalshi Eye. For the connection, choose a public endpoint URL and paste https://kalshieye.com/mcp. Choose OAuth sign-in.
  3. ChatGPT shows a warning about custom servers; accept it and create the server.
  4. Install it. A Kalshi Eye page opens: log in or create an account, then press Allow.

In a Business or Enterprise workspace, an admin may need to allow custom MCP servers before members can add one.

Use it in a chat

Start a new chat, type @ and pick Kalshi Eye, then ask. For example:

  • @Kalshi Eye which Polymarket and Kalshi markets are about the next Fed decision?
  • @Kalshi Eye how did KXBTC15M-26OCT251200-00 trade in its last ten minutes, and how did it settle?
  • @Kalshi Eye how complete was recording on each venue over the last week?
  • @Kalshi Eye which datasets have Coinbase files, and what columns do they have?
  • @Kalshi Eye list the settlements files for October 20 to 26 and give me download links.

Prices come back as dollars between 0 and 1, which read as the market's probability, and times in UTC. Before it gets download links, ChatGPT asks you to confirm. Every tool is listed on the MCP server page.

What it can't do

  • It only reads: it can't trade, place orders, or change your account, plan or keys.
  • It doesn't open the files itself. For analysis over many markets or days, use a coding agent such as Codex, which downloads and reads them.

Limits

Each tool call uses one or two API requests from your plan's daily limit; Explorer's 100 a day cover about 50 to 100 calls and reset at midnight UTC. Downloading the files counts toward your monthly download allowance. See plans.

Disconnect

Open API and press Disconnect next to ChatGPT under Connected apps. Removing the server inside ChatGPT doesn't end its access, so do both.

Questions

Why does ChatGPT ask me to confirm some calls?

ChatGPT asks before any tool that is not marked read-only. The one Kalshi Eye tool that isn't is download_links: it changes nothing, but the files it links count toward your monthly download allowance.

Does it work in Codex too?

Yes. Codex adds the same URL with codex mcp add; see the guide to Claude Code, Codex and Cursor.

Do I need a paid Kalshi Eye plan?

No. A free Explorer account connects and can search every market, read price history and coverage, and list files. Download links follow your plan.
