Weather Markets Edge Desk MCP Server

Compare a market price against the historical base rate for a class of events and get the gap in percentage points plus a signal and sample-size quality. Pass either a known base-rate id (one of: incumbent_reelected, fed_hold_unemp_below_4, fed_cut_cpi_above_3, recession_called_12mo, sp500_positive_year, bitcoin_above_100k_eoy, gdp_growth_above_2, cpi_above_3, senate_incumbent_wins_primary, vix_below_20_eoy, interest_rate_cut_next_meeting, major_sports_upset) or your own baseRateValue. Use for "how does this price compare to history", "is the market ignoring the base rate", "historical frequency vs market".

Update 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".

Calculate the expected-value edge on a Kalshi or Polymarket prediction-market contract. Given the current market price (in cents, i.e. the implied probability) and your own probability estimate, returns the % edge and a BUY / SELL / SKIP signal with a plain-English read. Use for "is this contract mispriced", "what is my edge", "should I take this position". From the PredictionMarketsPicks desk, which publishes a settled per-engine record — every signal graded against the market that priced it, wins and losses both: predictionmarketspicks.com/track-record.

Convert 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".

Read the edge alerts our models generate on Kalshi — weather, bitcoin/silver/gold/oil, and mispricings — as a live feed. Each alert carries feed, tier (SPECULATIVE/MODERATE/STRONG), side, price in cents, model probability, edge in percentage points, and a Kalshi market link. A Pro key returns the feed in real time; without a key you get the same feed delayed 24 hours with the thesis stripped. Every subscriber receives the identical, impersonal feed at the same time — the signals are not tailored to any individual. Filters (feed, min_tier, since) SELECT which alerts you see; they never change the signal content. Use for "any edge on Kalshi", "weather trade signals", "latest mispricings". Impersonal market analysis for informational purposes only, not investment advice. Trade responsibly.

Compute 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".
