NodusAI MCP Server

> AI-Powered Signals for Prediction Markets — accessible to any AI agent via MCP.

AI agents connect to this server to get Oracle signals for Polymarket and Kalshi prediction markets. Signals are generated by Gemini 2.5 Flash with real-time web grounding.

How it works

Agent → nodusai.app → connect wallet → pay $1 USDC → get session token
                                                              ↓
Agent → MCP Server (nodus_get_signal) → nodusai.app/api/prediction → signal

1. Visit nodusai.app and connect your wallet
2. Paste a Polymarket or Kalshi market URL
3. (Optional) Add your desired outcome (YES / NO)
4. Pay $1 USDC — confirmed on-chain
5. Get a session token good for 3 queries
6. Use the session token with nodus_get_signal in any MCP client

---

Payment model

- Cost: $1 USDC = 3 Oracle signal queries
- Networks: Base, Ethereum, Avalanche (any EVM chain)
- Token: USDC
- Non-custodial: payments go directly on-chain via nodusai.app
- Session: one payment = one session token = 3 queries (24h validity)

Signal format

Every Oracle response follows NodusAI's structured schema:

{
  "market_name": "Will the Fed cut rates in June 2026?",
  "predicted_outcome": "YES",
  "probability": 0.73,
  "confidence_score": "HIGH",
  "key_reasoning": "Recent FOMC minutes and inflation data suggest...",
  "grounding_sources": [
    { "title": "Reuters: Fed signals rate path", "url": "https://..." },
    { "title": "AP: CPI data June 2026", "url": "https://..." }
  ]
}
