### Description (declared)

# prediction-market-mcp 
 
> Give Claude (or any MCP-compatible LLM) a live view into **Polymarket + Kalshi + Manifold**, plus a single tool that hunts for **3-venue** arb. 
>  
> **Just want to look at Polymarket data without installing an MCP server?** Try the live dashboard: https://creampig666.github.io/prediction-markets-live/ 
 
An [MCP](https://modelcontextprotocol.io/) server in ~400 lines of Python. No keys, no auth, no signup. Stdio transport, Claude Desktop ready. 
 
``` 
You:  "Find me anything interesting on bitcoin right now." 
Claude (calls find_arb_opportunities("bitcoin")): 
  "Polymarket has 'BTC > $150k by Jun 30' at 12%. Kalshi's matched 
   contract is at 19%. Manifold's 'Bitcoin to $150k in 2026?' is at 22%. 
   12 percentage points between Polymarket and Manifold — worth a 
   look at whether they're really the same underlying..." 
```
