One URL, no API key. Add the PredictionMarketsPicks MCP server to Claude, ChatGPT, Grok, Cursor or Claude Code and your agent can price Kalshi and Polymarket contracts, pull this week's NFL prop board, and size a position — by calling the tools directly, not by scraping the site.
Quick Answer
to connect Claude, ChatGPT, Grok, Cursor or Claude Code to Kalshi prediction markets, add https://predictionmarketspicks.com/api/mcp/mcp to your host as a remote MCP server (Streamable HTTP). No API key and no account: 11 of the 26 tools answer immediately — EV edge, Kelly sizing, Bayesian updates, odds conversion, and the in-season NFL desk: every Kalshi prop this week venue by venue, spread and win-total ladders, correlation-aware same-game combos. Setup takes about a minute; the per-host steps are below.

https://predictionmarketspicks.com/api/mcp/mcpEvery host below takes the same URL; only the dialog differs. Note the /mcp twice — the base path /api/mcp on its own will not connect.
The same connector works in the Claude desktop app and on claude.ai — one URL, added once.
claude mcp add --transport http predictionmarketspicks https://predictionmarketspicks.com/api/mcp/mcp
Grok gets its own walkthrough because its path is genuinely different — the other hosts take a bare URL in one dialog, Grok has a connectors page.

}Pro tools take a PredictionMarketsPicks key as an Authorization: Bearer header on the same server URL. Keys are provisioned at checkout and live at /account/keys; the tier is $14.99/mo or $150/yr.
claude mcp add --transport http predictionmarketspicks https://predictionmarketspicks.com/api/mcp/mcp \ --header "Authorization: Bearer pmp_v2_pro_YOUR_KEY"
For JSON clients, add a "headers" object with the same Authorization value to the server entry above.
Sixty seconds: the connector added, then the prop board, the ladder, a same-game combo, the weekly edges and a position size — answered by the server's own tools. Scene-by-scene prompts are on the in-season NFL page.
Check the URL first: it ends in /api/mcp/mcp, with /mcp twice. The base path alone never connects. In Claude, a connector that was added but has gone quiet usually comes back by toggling it off and on under Settings → Connectors, or by retrying the message — the “Unable to reach PredictionMarketsPicks” line comes from the host's connector gateway, which sits between your chat and our endpoint, and appears even when every request that reaches us is answered. To check our side, open /api/health — a JSON response naming a commit means the server is up.
A greyed-out tool is the host saying the connector is not enabled for that conversation — enable it and start a new chat. Nothing on our side greys a tool: the free tools answer with no key, and a Pro tool called without a key answers with a one-line offer inside a normal response, never a disabled state or an error. If the tool list is empty rather than greyed, the URL is wrong (see above).
Not to start. 11 of the 26 tools answer with no key, no email and no account, at full depth. Pro ($14.99/mo) adds the live-edge tools — mispricing scans, cross-venue arbitrage, commodity edge and the weekly NFL game and player-prop edges — and is the same tier that unlocks them on the site. A Pro tool you call without a key tells you so in one line and points at /pricing.
One registry, three published views under the same DNS-verified namespace. quant — the URL on this page — exposes all 26 tools and is the one to install. fantasy-draft (https://predictionmarketspicks.com/api/mcp-draft/mcp) exposes only the 8 draft tools and is parked until the 2027 offseason — in season a call answers with a redirect to the NFL tools; the hub stays up at /draft. weather (https://predictionmarketspicks.com/api/mcp-weather/mcp) exposes the 6-tool Kalshi weather loop, landing at /weather. Both are strict subsets of quant — same tools, same caps, same unlock — so installing quant gives you everything.
Connected? Ask it something with a number in it.
No. Add https://predictionmarketspicks.com/api/mcp/mcp to your host as a remote MCP server and 11 of the 26 tools answer with no key, no email and no account — the calculators (EV edge, Kelly sizing, Bayesian update, odds conversion, base-rate gap) and the in-season NFL desk (every Kalshi prop this week venue by venue, the spread and win-total ladders, correlation-aware same-game combos). Only the Pro tools — live mispricing scans, cross-venue arbitrage, commodity edge and the weekly NFL game and prop edges — take a key, passed as an Authorization: Bearer header.
Yes. In ChatGPT, open Connectors in settings, turn developer mode on, add a remote MCP server and paste https://predictionmarketspicks.com/api/mcp/mcp. Leave authentication empty for the free tools. It is the same server ChatGPT, Claude, Grok, Cursor and Claude Code all connect to — one URL, and nothing about the tools or the data changes between hosts, only the setup dialog does.
The free tools cost nothing and never will — no key, no signup, rate limited per IP, full depth. Pro is $14.99 a month or $150 a year, the same tier that unlocks the tools on the site, and it adds the live-edge tools: mispricing scans, cross-venue arbitrage gaps, commodity edge and the weekly NFL game and player-prop edges. A Pro key is provisioned at checkout and lives at /account/keys; you paste it into the same connector as one extra header.
Any client that speaks Model Context Protocol over Streamable HTTP. The ones with a published path on this page are Claude Desktop, Claude.ai, Claude Code, ChatGPT, Grok and Cursor; Gemini and Copilot are named on the server page and take the same URL. There is nothing to install — the server is hosted, and the endpoint https://predictionmarketspicks.com/api/mcp/mcp is the canonical install answer for every host. The source is public at github.com/predictionmarketspicks/mcp if you would rather read the implementation.
