Veynor — Prediction Market Intelligence
Gives Claude direct access to live prediction market data from Kalshi and Polymarket through a single SSE endpoint. You can ask natural language questions about whale trades, arbitrage opportunities, and market sentiment, then place orders on Kalshi or relay signed Polymarket transactions. The query_intelligence tool automatically routes your prompt to the right data pipeline and returns AI-synthesized analysis. Includes alpha signals for price movers, wide spreads, and cross-venue arbitrage, plus historical price charts and topic-based market feeds for crypto, geopolitics, and macro events. Uses a credit system with 100 free credits monthly. Best for building trading bots, monitoring specific outcomes, or getting market-wide briefings without scraping HTML.

Veynor MCP Server
Prediction market intelligence for AI agents.
Real-time whale trades, market data, alpha signals, and AI-synthesized analysis from Kalshi and Polymarket — available as a Model Context Protocol server and REST API that any AI agent can connect to.
What is this?
The Veynor MCP server gives AI agents (Claude, Cursor, Windsurf, or any MCP-compatible client) direct access to live prediction market data. Instead of scraping websites or parsing unstructured HTML, agents get clean structured data through a standardized protocol — and can reason over it, summarize it, monitor it, and place trades in natural language.
Example prompts your agent can handle once connected:
- "What are whales betting on right now? Any large trades on Iran or tariffs?"
- "What are prediction markets saying about the Fed rate decision?"
- "Find markets where the bid/ask spread is unusually wide."
- "Is the same Fed rate decision priced differently on Kalshi vs Polymarket?"
- "Buy 10 contracts of KXIRANUKE-26 YES at 30 cents."
- "Any unusual volume spikes today? Give me a full signal scan."
