"Information about prediction markets and Polymarket platform" matching MCP tools:
- Search Polymarket for events and markets by name, topic, URL, or slug. **PM building blocks:** - An **event** is a grouped prediction topic containing many child markets. - A **market** is one tradable outcome with its own `marketId`. - Example: `2026 NCAA Tournament Winner` is an event; `Will Duke win the 2026 NCAA Tournament?` is a market. Detail tools require `marketId`, not `eventId`. **When to use:** - First tool when the user asks about a specific PM topic, event, slug, or Polymarket URL but does not provide `marketId`. - Optionally provide `queryVariant` as a cleaner short keyword version. - Set `includeEventMarkets` to true to also return child markets for the best-matching event. - Do NOT use `general_search` for prediction markets. - Results include current outcome prices, last trade price, and bid/ask inline — for a quick probability check you may not need `prediction_market_ohlcv`. For price *history* or dated moves, still use `prediction_market_ohlcv`. **Query tips:** - Uses Polymarket's search API — natural language queries work well. - Prefer short 1–3 keyword queries for best results. - Avoid broad multi-topic queries like `bitcoin ethereum politics`. **Output rules:** - If lookup returns no suitable market or a mismatched timeframe, say so explicitly — do not silently substitute a nearby market.Connector
- Get live World Cup 2026 odds: tournament winner probabilities for every team, all 12 group winners, knockout-round props, continent and Golden Boot specials, and 1/X/2 prices for upcoming matches.

- General search tool. This is your FIRST entry point to look up for possible tokens, entities, and addresses related to a query. Do NOT use this tool for prediction markets. For Polymarket names, topics, event slugs, or URLs, use `prediction_market_lookup` instead. Nansen MCP does not support NFTs, however check using this tool if the query relates to a token. Regular tokens and NFTs can have the same name. This tool allows you to: - Check if a (fungible) token exists by name, symbol, or contract address - Search information about a token - Current price in USD - Trading volume - Contract address and chain information - Market cap and supply data when available - Search information about an entity - Find Nansen labels of an address (EOA) or resolve a domain (.eth, .sol)Connector

Prediction market data and crowd-sourced probability forecasts

- Get high-level facts about the ACCRUE platform: fee structure, custody model, supported chains, wallets, KYC requirements, withdrawal terms, and AI agent integration status. Use this when the user asks "what is ACCRUE", "how does ACCRUE work", "what are the fees", or anything about the platform itself rather than a specific vault.Connector

- Scan weather prediction markets for expected-value edge — where the Weather Agent's probability estimate diverges from the market price. Weather is the live edge domain today. Results include public freshness metadata; stale signals are marked do_not_enter and paid unlocks only reveal active signals. Returns (public): redacted tracked-market samples plus a count of markets with a strong edge. Public results are not ranked by expected value because ranking with market identity would leak the signal. With a Bearer API key, GET may return opaque edge-ranked locked tickets (rank + bet side + edge only, no market identity). Use POST /api/edge/unlock-best with {"domain":"weather","rank":1,"max_cost_credits":1} to spend exactly 1 credit and reveal that ranked signal. POST /api/edge/unlock remains available when the caller already knows a specific market_id. Filters: platform (kalshi, polymarket), min_ev. The live domain is weather. Verified specialist available: domain="weather" pulls Kalshi and Polymarket daily-high temperature markets pre-scored by Weather Agent v1 for supported cities globally. Public leaderboard: https://www.licium.ai/leaderboard. Weather Agent details: https://www.licium.ai/agents/59d67bf8-53d3-4f10-8ddc-e6fed4d051ba.Connector
