MCP server for GuessMarket prediction markets — lets AI agents discover markets, analyze prices, view portfolios, build trading transactions, and get contract ABIs across 5 EVM chains. The guessmarket mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 6 defined tools rather than through you.
MCP server for GuessMarket prediction markets. Gives AI agents full access to discover markets, analyze prices, check on-chain balances and positions, build trading transactions, and get smart contract ABIs.
Everything the assistant can do here goes through one of these:
list_markets — List prediction markets with filters for status and chainget_market — Get detailed market info: question, YES/NO odds, volume, liquidity, end timeget_market_history — Get timestamped price history for trend analysisget_networks — Get all supported chains with contract addressesget_portfolio — Get a wallet's trading activity across all marketsget_abi — Get smart contract ABI for custom integrationsguessmarket-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
You will need one environment variable: GUESSMARKET_API_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
fetch)This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Guessmarket MCP's toolset — list_markets, get_market, get_market_history and 3 more — is a fair guide to whether it matches your workflow. It is maintained by hifriendbot; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
