Mantis is a remote MCP server that gives an AI agent 6 tools, among them execute_url, get_arbitrage, get_history. It answers at https://mantiss.store/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Cross-venue prediction market routing for AI agents with arbitrage, quotes, history, and signals.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
execute_url | Get a deep link URL to place a trade on the best venue for a given market. The URL has a referral code embedded so the platform earns commission. Call this to get the URL, then direct the user to open it. Inputs: market_id, canonical_id, side, amount, source, route_query |
get_arbitrage | Find live cross-venue arbitrage opportunities — markets where the same event trades at different prices on Polymarket vs Kalshi vs other venues. Can also estimate fee-normalized net spread for a position size. Inputs: min_spread_pct, include_fees, position_size, venue_a, venue_b |
get_history | Get historical OHLCV-style prediction market candles over a time range, including the latest stored depth snapshot within each bucket when available. Can also export CSV text or base64-encoded Parquet. Inputs: market_id, canonical_id, venue, from, to, granularity |
get_quote | Get the live probability, liquidity, and volume for a prediction market across all venues. Can also return venue order book depth and size-aware VWAP/slippage estimates. Inputs: market_id, canonical_id, size |
get_unmet_demand | Find questions that users are searching for but no prediction market exists. Useful for discovering new market creation opportunities or identifying emerging topics with real trading interest. Inputs: days, limit |
route_market | Find the best prediction market for a natural-language question or trading intent. Returns the best cross-venue match, current probability, liquidity, and any arbitrage opportunity between venues. Inputs: q |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mantiss.store/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.alfred768. Endpoint host: mantiss.store. ARD identifier: urn:air:io.github.alfred768:mcp:mantis.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
