Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

polybridge
polybridge_forecast
Generate a read-only probability forecast for a clearly stated future event by searching relevant prediction markets and synthesizing evidence. Use when the user asks for a probability, outlook, or forecast; use polybridge_search when they only need market discovery. Does not place trades, provide financial advice, or access private/internal data.
polybridge_search
Search public prediction markets for markets relevant to a natural-language topic or question. Use when you need candidate markets, market URLs, outcomes, statuses, and relevance scores. Do not use for a final probability forecast, market-history lookup, trading, or private/internal data. Scores are relevance scores, not probabilities.

PolyBridge — questions

Answers built from our own checks of this server.

What can PolyBridge do?
It exposes 2 tools, read directly from the server on our last check. Among them: polybridge_forecast, polybridge_search. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is PolyBridge working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 196 ms. The bar chart above shows every period we have measured.
How do I connect PolyBridge?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does PolyBridge need an API key?
No. PolyBridge completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is PolyBridge?
It answers our handshake in 196 ms on average, which is faster than 63% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
