NFL MCP Server — Kalshi Props, Spreads & Game Edges Inside Claude, ChatGPT & Grok

The same connector that ran the draft desk now prices the season. Connect once and ask in plain English: the best price on a prop across every venue, whether the model disagrees with Kalshi on the tail or the median of a spread, what a same-game combo is really worth once the legs are correlated, and which games are mispriced this week — then size the position. The free tools answer with no key and no account.

Sixty seconds: one connector, no API key, then the prop board, the ladder, a same-game combo, this week’s edges and a position size — answered by the server’s own tools. Watch on YouTube

Quick Answer

the PredictionMarketsPicks MCP server is the in-season NFL desk for an AI agent. Add https://predictionmarketspicks.com/api/mcp/mcp to Claude, ChatGPT, Grok, Cursor or Copilot and 10 tools answer with no key — nfl_prop_board prices every Kalshi prop this week venue by venue, nfl_ladder puts every spread, win-total and prop strike against the model's whole distribution, combo_edge prices a same-game combo with a correlation-aware joint, and kelly_size sizes the result. nfl_edge and nfl_prop_edge (the weekly game and player-prop edges against live Kalshi prices) are Pro — $11.09 for the first month with code NFL26. The engines behind the tools publish a graded record: 2,991 decided signals graded against the market that priced them, +$98.99 net on a flat one-contract stake — 31 of them since the current engine versions shipped, -$0.74 — published per tool, including the engines that lose money.

Five prompts, word for word

Each one below is a frame from the clip above, in the order it asks them. Say the prompt to a connected agent and it resolves to the named tool; every answer links back to the same numbers on this site.

nfl_prop_board output: Josh Allen 250+ passing yards priced on Kalshi, DraftKings, FanDuel, BetRivers and Novig/ProphetX, with the best over and best under venue named
1 · nfl_prop_board · Free

Where’s the best price on Allen 250+ pass yards?

Every venue. One prompt.

Every Kalshi prop strike with a real two-sided book, the book consensus at that exact strike, the DraftKings / FanDuel / BetRivers lines, the Novig and ProphetX quotes, the Kalshi-vs-consensus gap in cents — and where the best price for each side actually is, Kalshi net of fee.

nfl_ladder output: the Kalshi KXNFLSPREAD ladder for the Bills with the model probability at each strike and the verdict SHAPE
2 · nfl_ladder · Free

Where does the model disagree with Kalshi on the Bills spread — the tail or the median?

Shape or location — the ladder tells you which.

Every Kalshi strike on a spread, season win total or player prop beside our whole probability distribution, ranked by the widest published gap, with the derived verdict: SHAPE (we disagree about the tail, not the middle), LOCATION (we think the median sits elsewhere) or PRICED. Our number is published only between 30% and 70%, where it is measured calibrated.

The Ladder on the site

combo_edge output: the naive product of two leg prices beside the correlation-aware joint probability, the fair odds band, and the verdict RUN with a negative-correlation-trap flag
3 · combo_edge · Free

Price Allen 250+ pass yds at 55¢ with BUF moneyline at 60¢ — Kalshi quotes +250.

Correlation-aware. Not the naive product.

Pass a game and the tool lists that game’s real Kalshi legs — moneyline, spreads, the total ladder and player props, both sides of every contract. Pass leg ids and it prices the exact combo with a correlation-aware joint from the scoreline model, a fair-odds band, and a 7-tier verdict against the price you were quoted. A prop is priced conditional on the game script, so four unders that all need a low-scoring game are priced as the correlated slip they are.

Which NFL games are mispriced on Kalshi this week?

The wall is honest. So is the number.

nfl_edge is a Pro tool, and the wall tells you what is behind it before asking for anything: how many game edges of 4pp or more sit against live Kalshi prices right now, and the largest one. Pro returns the matchups, the model probability and the side — plus nfl_prop_edge for the player props.

What the wall says right now14 NFL game edges ≥4pp against live Kalshi prices — largest 15pp. Pro returns the matchups, the model probability, and the side. 94 NFL player-prop edges ≥5pp against the Kalshi lines — largest 29pp. Pro returns the players, the projection, and the side.

kelly_size output: the quarter-Kelly stake in dollars, the number of contracts, and the percentage of a $500 bankroll
5 · kelly_size · Free

Quarter-Kelly that at 15.3pp on a $500 bankroll.

Then size it.

Win probability, contract price, bankroll and a Kelly fraction in; the stake in dollars, the applied fraction and a risk rating out. An edge is disagreement with the market, not a guarantee — sizing is where that sentence becomes a number.

Frequently Asked Questions

Is there an MCP server for NFL prediction markets?

Yes. The PredictionMarketsPicks MCP server exposes its NFL model and the live Kalshi NFL board as tools any MCP client can call — Claude, ChatGPT, Grok, Cursor or Copilot. In season the NFL tools are nfl_prop_board (every Kalshi prop strike this week priced venue by venue), nfl_ladder (every spread, win-total and prop ladder against the model's whole distribution), combo_edge (a correlation-aware same-game combo), nfl_power_ratings, nfl_win_probability, and the Pro pair nfl_edge and nfl_prop_edge. Endpoint: https://predictionmarketspicks.com/api/mcp/mcp (Streamable HTTP).

Can Claude or ChatGPT get Kalshi NFL prop prices?

Once the server is connected, yes. Ask "where is the best price on Puka Nacua receiving yards" and the agent calls nfl_prop_board, which returns every Kalshi strike with a real two-sided book, the book consensus at that strike, the DraftKings, FanDuel and BetRivers lines, the Novig and ProphetX quotes, and where the best price for each side is — cents per dollar of payout, Kalshi net of fee. Every row carries the Kalshi market link and the matching page on this site. No API key is needed.

Which of the NFL tools are free?

10 tools answer with no key and no account right now: calculate_ev, kelly_size, bayes_update, convert_probability, base_rate_gap, combo_edge, nfl_power_ratings, nfl_win_probability, nfl_ladder, nfl_prop_board. nfl_edge and nfl_prop_edge are Pro tools — the wall they return is a 200 with the live count and largest edge in it, never a bare refusal. Pro is $11.09 for the first month with code NFL26, then $14.99/mo.

What happened to the fantasy draft tools?

They are parked for the season. From September 10, 2026 the 8 draft tools (draft_board, best_available, player_outlook, explain_player, compare_players, sleepers_and_busts, adp_market_gaps, who_do_i_draft) answer with a redirect to the in-season tools rather than a board — the connector stays connected and nothing needs reinstalling. They come back for the 2027 offseason at predictionmarketspicks.com/draft. Fantasy football was the bridge; pricing the real season against Kalshi is the product.

What does SHAPE vs LOCATION mean on the Ladder?

A Kalshi spread, win total or player prop trades as a ladder of strikes. nfl_ladder puts the Kalshi price at every strike beside our full probability distribution and names the disagreement: SHAPE means the gap changes sign across the ladder — we disagree about the tail, not the middle; LOCATION means every rung leans the same way — we think the median sits somewhere else; PRICED means the gap is under 5pp everywhere. Our number is published only between 30% and 70%, where it is measured to be calibrated; outside that band the tool returns the market only.

Does combo_edge account for correlation between legs?

Yes — that is the point of it. Multiplying two leg prices assumes the legs are independent, and a quarterback's passing-yards prop is not independent of his team's moneyline. Pass an NFL game and combo_edge lists that game's real Kalshi legs; pass the leg ids and it computes the correlation-aware joint probability from the scoreline model, returns the fair-odds band, flags a negative-correlation trap, and grades the price you were quoted on a 7-tier scale from SMASH to RUN. Props are priced conditional on the game script — pace from the total, flow from the margin — inside the same model as the game legs.

How do I connect it?

Add https://predictionmarketspicks.com/api/mcp/mcp as a remote MCP server. In Claude Desktop or Claude.ai it is a custom connector; in ChatGPT it is under connectors / developer mode; in Grok it is grok.com/connectors → New Connector → Custom; from Claude Code run claude mcp add --transport http predictionmarketspicks https://predictionmarketspicks.com/api/mcp/mcp. Note the /mcp twice — the base path /api/mcp on its own will not connect. No key is needed for the free tools; Pro tools take a PredictionMarketsPicks API key as an Authorization: Bearer header.

Is Kalshi a sportsbook?

No. Kalshi is a CFTC-regulated event-contract exchange — a prediction market where every NFL contract is a YES/NO position that settles at $1 or $0. The tools treat each one as a probability problem: our number against the market price, the edge in percentage points, and the position size that edge supports. Every signal our engines publish is settled against the market that priced it and graded in public at predictionmarketspicks.com/track-record, losses included. Educational analysis, not financial advice.
