Overview

AI-generated overview

Remote MCP server for Polymarket prediction markets: live odds, order books, fee-inclusive quotes, positions and non-custodial trading setup.

What you can do
  • Search events and markets with live odds, filters, token ids and human URLs
  • Read a full event, its markets, rules, resolution source and recent trades
  • Inspect live order books, spreads, midpoints and price history per outcome token
  • Preview orders against the live book with average price, cost, payout and fees
  • Get non-custodial trading setup, attestation messages and a 30-day agent token
  • Create pre-filled trade links, and read positions and trader leaderboards
When to use it
Useful when an assistant needs to research prediction-market odds, compare prices or order books, or prepare a trade for a human or a self-custodied agent wallet. It suits analysis and quote previews rather than hands-off automated trading.
Requirements
A remote streamable HTTP endpoint; no package, environment variables or headers are declared. Trading setup assumes the user has their own wallet and signs with their own key; attestation requires an EIP-191 signature within 10 minutes. Network access to the endpoint is required.
Before you install
Trading involves real money and fees from both Polymarket and predictDEX. The server is non-custodial and attestation grants no custody, but the 30-day agent token unlocks gasless account setup through predictDEX's signer for your address. Signing requests should be reviewed; trade links execute nothing until a person signs. Region rules still apply.

Installation

In SourceWeft

  1. Open predictDEX in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/mk.dex%2Fpredictdex/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
