Tools & capabilities
Predictionmarketspicks MCP tools 34
fed_rate_oddsUse for "will the Fed cut, hold or hike" and "next FOMC meeting odds". Live Kalshi odds for each remaining 2026 FOMC meeting: the next meeting's full strike breakdown and days-until, the rate path, the current fed funds rate, and a next-meeting cross-venue check against Polymarket and CME futures, with the gap in pp. Free, no key.calculate_evUse for "is this contract mispriced" and "what is my edge". Give a Kalshi or Polymarket price in cents and your own probability; returns the % expected-value edge and a BUY / SELL / SKIP read. Free, no key. Every PMP engine signal is graded in public: predictionmarketspicks.com/track-record.kelly_sizeCompute the optimal Kelly position size for a prediction-market contract. Given your win probability, the market price (which sets the payout), your bankroll, and a Kelly fraction (full / half / quarter / eighth), returns the dollar stake and a risk rating. Use for "how much should I stake", "what is my position size", "Kelly sizing for this trade".bayes_updateUpdate a prior probability with one or more pieces of evidence using Bayes theorem. Given a prior and a list of evidence items (each with P(evidence | true) and P(evidence | false)), returns the posterior probability and the per-step chain. Use for "update my estimate with new information", "posterior probability", "how does this news change the odds".convert_probabilityConvert between implied probability, American odds, and decimal odds. Give one value and its format and get all three back (American odds carry no commas, e.g. +441 or -200). Use for "what is +150 as a probability", "convert 62% to American odds", "decimal to implied odds".base_rate_gapUse for "how does this price compare to history" and "is the market ignoring the base rate". Compares a market price with the historical base rate for a class of events: the gap in pp, a signal, and sample-size quality. Pass a known baseRateId (the parameter lists them) or your own baseRateValue. Free, no key.combo_edgeUse for "price a same-game NFL combo" and "is this combo worth it". Pass nflGame ("NYG-LAR", "Giants vs Rams") to list that game's Kalshi legs — moneyline, spreads, totals, player props — then legIds to price your pick with the correlation done for you. Or pass legPrices + trueWinProbability for a fair band; add offeredOdds for EV and a verdict. Free.nfl_power_ratingsThe PredictionMarketsPicks NFL power ratings — PWR for all 32 teams: points per game above an average team on a neutral field, where PWR = Off PR + Def PR + ST PR. Includes each team's rank and tier. Free, no key. Use for "best NFL teams by power rating", "NFL power rankings 2026", "is Baltimore overrated", "how good is Kansas City", "NFL team ratings".nfl_win_probabilityUse for "who wins Chiefs vs 49ers" and "what does a -7 spread mean". Pass homeTeam + awayTeam (or game, or one team) for our QB-gated model line (raw power ratings if unscheduled), or a spread (home favored negative). Returns win, cover and over/under probability, the projected score and our own total; neutral-site games get no home edge. Free, no key.find_arbitrageUse for "where is the arbitrage" and "Kalshi vs Polymarket price gaps". Cross-venue gaps on the same sports contract (NBA, NHL, MLB, World Cup) against Polymarket's international book: the gap in pp, the WATCH/ARB signal and the cheaper venue. Free: the top 3 gaps in full; Pro returns the whole board.market_pulseThe US macro-health composite (0–100) and regime plus the six category scores (growth, labor, inflation, rates, liquidity, sentiment).

The Kalshi daily gold, silver or WTI strike, or hourly bitcoin strike, with the largest PMP model edge, as a ticket: side, entry price, resolve criterion, model probability, edge, tier and quarter-Kelly size. Pass tickers[] to check a watchlist. Pro — sign in with PredictionMarketsPicks, or a Pro API key.- +22 more on the listing page
Signal8 MCP tools 101
search_companiesSearch for companies by name or ticker symbol in the Signal8 database. Returns matching companies with their ticker, name, CIK, and exchange. Use this as the first step to find a company before calling other tools.get_company_profileGet an enriched company profile by ticker symbol. Returns CIK, exchange, sector, industry, market cap, employee count, description, and other fundamental data. This is a lightweight lookup (1 credit) -- use this when you only need basic company info rather than the full bundle. Always includes halted/haltCode/haltedAt trading-halt status (false/null when trading normally); a halted-but-listed ticker reports delisted:false.get_quoteGet the current stock quote for a company including price, volume, change, market cap, and other real-time market data. Use this when a user asks about a stock's current price or trading activity. Always includes halted/haltCode/haltReason/haltedAt/resumptionAt trading-halt fields (false/null when trading normally); a halted ticker returns the last-known quote instead of an error, or currentPrice:null + halted:true when nothing is recoverable.get_market_metricsGet computed market metrics for a company including volume averages, volatility, SMAs, and trend direction. Use when analyzing trading patterns or technical indicators beyond the basic quote.get_short_interestGet short interest data for a company including short volume, short ratio, days to cover, and short percent of float. Use when analyzing bearish sentiment or potential short squeeze setups.get_floatGet float data for a company: floatShares, source, floatDefinition, and as-of date. Use when analyzing share supply. IMPORTANT: check "floatDefinition" to know which float you are reading — "tradeable" (shares outstanding minus affiliates minus restricted/unregistered blocks: what can actually reach the tape; used on filing-derived dilution-snapshot tickers), "non_affiliate" (the SEC I.B.6 figure, which INCLUDES restricted shares held by non-affiliates — not what a trader means by float), "non_affiliate_estimate" (approximated from ownership filings), or "free_float" (vendor methodology). On snapshot tickers "nonAffiliateFloatShares" carries the SEC I.B.6 figure separately — it is the ONLY correct input to baby-shelf / I.B.6 shelf-capacity math; never use the tradeable float there, and never present the non-affiliate figure as tradeable supply. floatShares:null with "floatWithheldReason" set ("restricted_blocks_unnetted" | "stated_figure_impossible" | "affiliate_basis_stale" | "affiliate_figure_declined") means the figure was deliberately WITHHELD, not unavailable — do not substitute a vendor float. On "affiliate_basis_stale", "affiliateBasis.floatLowerBound" / "floatUpperBound" are a RANGE the float lies in (both ends or neither; null = not measurable) — a range to state, never a number to compute with. "restrictedShares":null means NOT MEASURED (a block exists whose size the filings do not state), NEVER zero; "restrictedBlockCount":0 is an answer, not an absence. "affiliateBasisStale" (with basisSpanDays/affiliateAnchorDate) labels a float whose affiliate table is materially older than its share count — the number itself is unchanged.get_float_historyGet the POINT-IN-TIME float history for a company — one sample per trade date (float shares, shares outstanding, and the source the float came from). Use to answer "what was the float on date X" or to see float expand across a dilution event, which the latest-only get_float cannot show. IMPORTANT: this series is FORWARD-ONLY — it began accumulating in mid-2026 and is NOT backfilled, so early/absent history is expected and an empty rows array is a normal result, not an error or a delisted company. Each row carries "source" ("polygon" | "computed" | "sec_10k" | "fmp") because float quality varies by provider — weigh rows accordingly rather than treating all sources as equal. Charged per your API tier.get_historical_pricesGet historical OHLCV price candles for a stock. Supports daily, weekly, and monthly resolutions. Use period shorthand (1M, 3M, 6M, 1Y, 5Y, ALL) or explicit from/to UNIX timestamps. Default is 1 year of daily candles. Use this to compute price returns, chart price history, or analyze volume trends over time.get_stock_price_changeGet percentage price changes for a stock across multiple timeframes: 1D, 5D, 1M, 3M, 6M, YTD, 1Y, 3Y, 5Y, 10Y, and MAX. Use this for quick "how much is it up/down" answers without fetching full candle data.get_financialsGet income statement, balance sheet, and cash flow data for a company. Supports annual, quarterly, and trailing-twelve-month views. Use when analyzing revenue, profitability, debt, or cash position.get_earningsGet historical earnings data for a company including EPS actual vs estimate, revenue actual vs estimate, and surprise percentages. Use when analyzing earnings beats/misses or upcoming earnings expectations.get_executivesGet key executives and officers of a company including name, title, compensation, and tenure. Use when researching company leadership or management quality.- +89 more on the listing page
