Available tools 4

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

chamber
chamber_outlook
Who is favoured to control the Senate or House after 2026: control probability, expected seats with an 80% range, how far it has moved since January, and the races that have moved most since the current model began (its latest revision).
forecast
forecast_race
Current VotePredictor forecast for one 2026 US election: win probability, predicted margin, whether it comes from polls or fundamentals, how far it has moved this cycle, and the candidates. Accepts a state name or code ('Ohio', 'OH') or a district ('CA-12'). Returns an explicit refusal for races where a candidate has left the ballot and no forecast is published.
forecaster
forecaster_accuracy
How accurate each election forecaster, model, prediction market and pollster has been on resolved races, adjusted for how hard each race was. Use this to answer 'whose election forecast should I trust'. Difficulty adjustment matters: on raw scores whoever rated the safest races wins.
member
member_profile
A member of Congress by name or bioguide id: party, state, ideology score, reported net worth from financial disclosures, and the 2026 race for their seat.

VotePredictor Elections — questions

Answers built from our own checks of this server.

What can VotePredictor Elections do?
It exposes 4 tools, read directly from the server on our last check. Among them: chamber_outlook, forecaster_accuracy, forecast_race, member_profile. 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 VotePredictor Elections working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 3 of 92 checks got a reply (3.3%), average response time 416 ms. The bar chart above shows every period we have measured.
The registry lists VotePredictor Elections as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect VotePredictor Elections?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does VotePredictor Elections need an API key?
No. VotePredictor Elections completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is VotePredictor Elections?
It answers our handshake in 416 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
