Overview

AI-generated overview

PolyBridge lets an assistant search public prediction markets and generate read-only probability forecasts for future events from live market signal.

What you can do
Search public prediction markets by natural-language topic or question, returning candidate markets, URLs, outcomes, statuses and relevance scores. Generate a read-only probability forecast for a clearly stated future event by searching relevant markets and synthesizing the evidence.
When to use it
Useful when a user wants market discovery around a topic, or asks for a probability, outlook or forecast on a future event and you want prediction-market signal behind the answer.
Requirements
A remote MCP endpoint reached over streamable HTTP; no packages, environment variables or headers are declared.
Before you install
Forecasts are read-only and do not place trades or provide financial advice; relevance scores are not final probabilities. The server does not cover market-history lookup, trading or private/internal data.

Installation

In SourceWeft

  1. Open PolyBridge 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/io.github.crowdvector%2Fpolybridge-mcp/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

Other MCP clients

Add this to your client's mcpServers config.

PolyBridge Forecast

Generate a read-only probability forecast for a clearly stated future event by searching relevant prediction markets and synthesizing evidence.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
