Prediction Markets MCP Server — 34 Quant Tools for AI Agents
PredictionMarketsPicks — founded by Benny Ricciardi, with analysis from The 7 Oracles — exposes its quant toolkit as an MCP server, so an AI agent can call our calculators instead of scraping the site. Connect Claude, ChatGPT, Gemini, Cursor, or Copilot and run expected-value, Kelly sizing, Bayesian updates, odds conversion, and base-rate checks on any Kalshi or Polymarket contract directly in the chat.
Transcript
The draft’s over. Your agent isn’t.
Add a custom connector: predictionmarketspicks.com/api/mcp/mcp. No API key. Works in Claude, ChatGPT and Grok. 27 free tools.
“Where’s the best price on Allen 250+ pass yards?” nfl_prop_board — Kalshi, DraftKings, FanDuel, BetRivers, Novig/ProphetX side by side. Every venue. One prompt.
“Where does the model disagree with Kalshi on the Bills spread — the tail or the median?” nfl_ladder — the full KXNFLSPREAD ladder, our number against the Kalshi price. Shape or location: the ladder tells you which.
“Price Allen 250+ pass yards at 55 cents with the Bills moneyline at 60 cents — Kalshi quotes +250.” combo_edge — naive product 33.0%, correlation-aware joint 30.0%. Fair +233. Verdict: RUN. Correlation-aware. Not the naive product.
“Which NFL games are mispriced on Kalshi this week?” nfl_edge — 14 game edges of 4 points or more against live Kalshi prices; largest 15.3pp. The wall is honest. So is the number.
“Quarter-Kelly that at 15.3pp on a $500 bankroll.” kelly_size — $36.78, 76 contracts, 7.4% of bankroll. An edge is disagreement, not a guarantee.
predictionmarketspicks.com/mcp. Free, no API key. Pro $14.99/mo — code NFL26, 26% off. /track-record: every signal graded against the market that priced it.
The on-screen chip in the cut says ten; the free surface has grown since it was filmed, and the count above is read from the server.
The end card's offer has changed: NFL26 now applies to the annual plan — $111 your first year, then $150/yr. Monthly is $14.99/mo.
Quick Answer
the PredictionMarketsPicks MCP server lets an AI agent call our prediction-market quant tools directly. Add the remote server at https://predictionmarketspicks.com/api/mcp/mcp to any MCP client (Claude, ChatGPT, Cursor, Copilot). The calculator tools — EV edge, Kelly sizing, Bayesian update, odds conversion, base-rate gap — are free and uncapped with no key, and so is the in-season NFL desk — every Kalshi prop this week venue by venue, the spread and win-total ladders, and correlation-aware same-game combos — with no key, no email and no signup (the fantasy draft desk is parked until the 2027 offseason).

No API key is needed to call any of the free tools — the calculators plus the whole in-season NFL desk, all at full depth. In season, 8 of the fantasy draft tools answer from this week's NFL board and the other 0 park until the 2027 offseason with a redirect to those tools. Pro tools take a PredictionMarketsPicks API key as an Authorization: Bearer header. The manifest lives at /.well-known/mcp/server.json.
Three focused servers publish under the same DNS-verified namespace. All three are subsets of the endpoint above — same tools, same caps, same unlock — for agents where a shorter menu is worth more than reach:
- Fantasy draft server —
https://predictionmarketspicks.com/api/mcp-draft/mcp. The draft desk and nothing else. - Weather markets server —
https://predictionmarketspicks.com/api/mcp-weather/mcp. The live Kalshi weather edge feed plus the calculators that turn a forecast into a position. - Commodity markets server —
https://predictionmarketspicks.com/api/mcp-commodities/mcp. Kalshi gold, silver, oil and crypto: the 15-minute board, perps and liquidation, and the model ticket.

- No key — 300 requests/minute per IP. Everything free answers at full depth: the calculators, the single-player lookups, and the entire fantasy draft desk.
- A burst throttle is the only remaining floor — sustained scraping drops to a small slice for ten minutes, then restores itself.
- Pro key — 5,000 requests/hour per key, uncapped depth, plus the Pro tools.
- Enterprise key — 100,000 requests/hour per key.
Pro data reads are served from a 60-second cache, so repeated calls inside a minute are free of upstream latency.
Use it with Kalshi Pro
The Kalshi Pro terminal shows you what's moving — price, spread, depth, 5-minute volume. It does not tell you what's mispriced. Copy the tickers from your Kalshi Pro screener or Canvas watchlist, paste them into your agent, and the ticker-addressable tools (nfl_edge, commodity_edge) return PMP's edge on exactly those markets. Tickers we don't model come back as not_covered — never a fabricated number.
“Here's my Kalshi Pro NFL watchlist: KXNFLWINS-27KC-11, KXNFLWINS-27BUF-11, KXNFLMVP-26. Run nfl_edge on these and tell me which are mispriced.”

Prediction Markets MCP Server — FAQ
What is the PredictionMarketsPicks MCP server?
It is a Model Context Protocol (MCP) server that exposes PredictionMarketsPicks quant tools as callable functions inside any MCP-compatible AI agent — Claude, ChatGPT, Gemini, Cursor, or Copilot. Instead of scraping the site, an agent can call the expected-value, Kelly sizing, Bayesian update, odds-conversion, and base-rate tools directly and get structured numbers back. It uses the Streamable HTTP transport at https://predictionmarketspicks.com/api/mcp/mcp.
Is the MCP server free?
Yes — the calculator tools (EV edge, Kelly sizing, Bayesian update, probability/odds conversion, base-rate gap) are free with no API key, rate limited per IP, and never capped. So is the NFL desk — nfl_prop_board, nfl_ladder, nfl_power_ratings, nfl_win_probability and combo_edge — and the 2026 midterms desk — senate_map and race_odds — with no key, no email and no signup, and so is the fantasy draft desk (in the NFL season draft_board, best_available, sleepers_and_busts, adp_market_gaps, who_do_i_draft, compare_players, explain_player, player_outlook answer from the week's NFL prop board, and the 0 draft-board tools park until the 2027 offseason with a redirect to the in-season tools). Live-data edge tools (NFL edges, commodity edge, the full cross-venue price-gap board) are the paid Pro tier ($150/yr, or $14.99/mo) and require a PredictionMarketsPicks API key passed by the agent.
How do I connect Claude or ChatGPT to it?
Add the remote MCP server URL https://predictionmarketspicks.com/api/mcp/mcp to your client. In Claude Desktop or Claude.ai, add it as a custom connector. In ChatGPT, add it under connectors / developer mode. In Cursor or Copilot, add it to your MCP settings JSON with a streamable-http (HTTP) transport pointing at that URL. No key is needed to start calling the free tools.
What can the tools actually do?
calculate_ev returns the percentage edge and a BUY/SELL/SKIP signal for a contract given its price and your probability. kelly_size returns the optimal position size for a bankroll. bayes_update chains evidence into a posterior probability. convert_probability moves between implied probability, American odds, and decimal odds. base_rate_gap compares a market price to a historical base rate. Every result links back to the full interactive tool on the site.
Are these prediction markets the same as a sportsbook?
No. Kalshi and Polymarket are CFTC-regulated event-derivative exchanges, not sportsbooks. The MCP tools treat every contract as a probability problem — expected value, calibration, and position sizing — the same quant framework a bond or options desk runs. Educational analysis, not financial advice.
Is there an MCP server for Kalshi and Polymarket?
Yes. The PredictionMarketsPicks MCP server is a prediction-markets MCP for Kalshi and Polymarket. It exposes quant tools an AI agent can call directly — an EV calculator, Kelly sizing, Bayesian updating, probability/odds conversion, base-rate gap analysis, and same-game combo grading — plus Kalshi vs Polymarket price gaps, macro pulse, and Pro commodity and NFL edge tools. Endpoint: https://predictionmarketspicks.com/api/mcp/mcp (Streamable HTTP).
Claude says 'Unable to reach PredictionMarketsPicks' — is the server down?
Almost always no. That message comes from your client's connector gateway, which sits between your conversation and our endpoint, so it appears even when every request that reaches us is answered normally. The fix is usually to retry the message, or toggle the connector off and on under Settings → Connectors. To check our side yourself, open https://predictionmarketspicks.com/api/health — it returns the exact commit production is serving, so a JSON response means the server is up. A GitHub-hosted probe also calls the live MCP endpoint end to end every 30 minutes from outside our infrastructure, and a genuine outage pages us.
Does the PredictionMarketsPicks MCP server have a track record?
Yes, and it is published rather than claimed. Every signal our edge engines put out is settled against the market that priced it and scored wins-and-losses on a flat one-contract stake — the per-engine table is on this page and the full ledger is at https://predictionmarketspicks.com/track-record. Engines that lose money are listed too, which is the point: a record that only shows winners is marketing, not evidence. Two caveats we state on the page itself — the net figure is a SUM over one-contract stakes and is never a per-contract average, and an engine with fewer than 20 decided signals is not listed at all, because a handful of settles is not a record.
Is the MCP server open-source?
The source is public and MIT-licensed at github.com/predictionmarketspicks/mcp, but you do not install anything to use it. It is a hosted server: add the remote URL https://predictionmarketspicks.com/api/mcp/mcp to your MCP client and the tools appear, no clone, no build, no local process, and the free tools need no key. The repository is there for reading the implementation or self-hosting a copy; the hosted endpoint is the canonical way to use it and the one the official registry lists.
Is the PredictionMarketsPicks MCP server verified?
Yes. It publishes under the DNS-verified namespace com.predictionmarketspicks/quant on the official Model Context Protocol registry (registry.modelcontextprotocol.io), authenticated by a DNS TXT record on predictionmarketspicks.com. That verified namespace is how AI agents and registries confirm the server is the genuine PredictionMarketsPicks prediction-market tools endpoint. We publish a second entry under the same verified namespace, com.predictionmarketspicks/fantasy-draft at https://predictionmarketspicks.com/api/mcp-draft/mcp, which is a fantasy-football-only view of the draft tools already on this server — a filtered subset, not a different product. A third entry, com.predictionmarketspicks/weather at https://predictionmarketspicks.com/api/mcp-weather/mcp, does the same for Kalshi weather markets: the live weather edge feed plus the calculators that turn a forecast into a position, landing at https://predictionmarketspicks.com/weather. A fourth, com.predictionmarketspicks/commodities at https://predictionmarketspicks.com/api/mcp-commodities/mcp, covers Kalshi gold, silver, oil and crypto — the 15-minute board, perps and liquidation, and the model ticket — landing at https://predictionmarketspicks.com/commodity-markets. This endpoint is the superset of all four and stays the recommended one.
