Why it exists

To know what markets think about BTC right now, you'd open Polymarket (hundreds of markets), then Hyperliquid perps (funding, OI), then cross the two manually. Nobody does this consistently.

With PredMCP, one question to your agent gets everything aggregated and cross-referenced in real time.

Example output

HL perps:  BTC $79,740 | funding +0.0000125 | OI 31,100 BTC   (slightly bullish)
HIP-4:     BTC > $81,041 by 6am  →  YES 12%                  (very bearish)
Signal:    DIVERGENCE — perps slightly bullish, prediction market very bearish

Output of get_signals('BTC'). The kind of cross-venue read no single API gives you.

Tool	What it does
`get_signals`	Cross Hyperliquid perp funding with HIP-4 and Polymarket sentiment for any asset.
`get_market_context`	Aggregates all Polymarket + HIP-4 markets + HL perp data for a topic or asset.

`get_hl_funding_pm_correlation`	Per asset, finds correlated PM markets and computes alignment vs divergence.
`get_hip4_vs_pm_arb`	Compares YES prices for the same event on HIP-4 and Polymarket. Returns exploitable spreads.

Add the MCP endpoint to your client config:

{
  "mcpServers": {
    "predmcp": {
      "url": "https://predmcp.com/mcp",
      "headers": { "x-api-key": "YOUR_KEY" }
    }
  }
}

That's it. Restart your client and the 22 tools are available.

Honest scope

A few things PredMCP does not do, so you can plan accordingly:

No HIP-4 order book depth — get_orderbook is Polymarket only.
No HIP-4 price history or candles.
No trading. Read-only data.
No push notifications or alerts. Pull-based only.
No long-range backtest data.
