Overview

AI-generated overview

Read-only market data server for prediction markets and crypto perps, letting an assistant query Polymarket, Hyperliquid and HIP-4 odds, funding, whales and…

What you can do
  • Search, list and read prediction markets with odds, orderbooks, movers, volume spikes and near-resolution markets
  • Read Hyperliquid perp data: funding rates, whale trades, open interest, orderbook depth and slippage, OI caps
  • Pull macro and price context: price summaries, DXY/yields/S&P/gold/VIX, crypto news headlines, options IV, ETF and stablecoin flows
  • Scan for mispricing and cross-venue signals: fair-value edges, Polymarket vs Hyperliquid divergences, HIP-4 vs Polymarket arbitrage, conviction and setup-quality scores
  • Backtest signals and inspect whale wallets, catalysts and market regime
When to use it
Useful when an assistant needs live prediction-market or perp-market context for research, signal scanning or trading analysis, while the user keeps execution entirely outside the assistant.
Requirements
Remote hosted endpoint at predmcp.com over HTTP transport; a required API key sent in the x-api-key header, obtained by email signup (free tier: 100 calls/day, one key per IP). Self-hosting the open-source core needs Node.js and npm.
Before you install
The API key is a secret sent in the x-api-key header. The server is read-only by design and asks for no wallet keys or seed phrases, but its outputs are market data and heuristic signals, not advice. Queries and topics go to a third-party hosted service, and some tools are described as Pro or early-access, so availability may change.

Installation

In SourceWeft

  1. Open PredMCP in the dashboard and add it to a workspace.
  2. Connect x-api-key credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.RavioleLabs%2Fpredmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

PredMCP

Safe, read-only market data for AI trading agents.

44 MCP tools that cross Polymarket prediction markets, Hyperliquid perps, and HIP-4 native predictions. Plug your agent into live trading data — without ever giving it the ability to execute orders.

Live, hosted, free during early access: predmcp.com

Why read-only matters

The #1 worry when wiring an LLM to a trading venue is the same in every conversation: "and it can't actually trade, right?" PredMCP is built so that question has a single answer.

  • No execution endpoint. Zero order-placement code exists in this codebase. Not gated, not commented out — not implemented. There is nothing to enable.
  • No private keys touched. We use the public Hyperliquid Info API and Polymarket Gamma API. Your wallet, your seed phrase, your accounts — never seen, never asked for.
  • 44 tools, all queries. Markets, orderbooks, funding rates, whale activity, signals. Every tool is a read. Your agent reasons about markets; you stay the only one who can act on them.

Examples

Iran — what prediction markets say right now:

"US x Iran peace deal by May 15"    → YES 20%  ($9M volume)"US x Iran peace deal by May 31"    → YES 34%  ($16M volume, +4% today)"Iranian regime falls before 2027"  → YES 15%  ($17M volume)"US invades Iran before 2027"       → YES 21%  ($26M volume)

One get_market_context call.

BTC cross-platform signal:

HL perps:  $79,740  |  funding: neutral  |  OI: 31,100 BTCHIP-4:     BTC > $81,041 by 6am tomorrow  →  YES 12%  (market says no)Signal:    ✓ ALIGNED — perps neutral, prediction bearish

When these diverge, it's a signal. get_signals computes it.

24h movers:

"Will Bitcoin hit $150k by June 30?"   $5.8M traded in 24h"US x Iran permanent peace deal"       $3.2M in 24h  (+4% move)Athletics vs Phillies                  +55% price move

Use the hosted server (recommended)

Get a free API key (email, no credit card, 100 calls/day) at predmcp.com/signup, then drop into your claude_desktop_config.json:

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

Also works with Cursor, Windsurf, Claude.ai (OAuth), and any MCP client that supports HTTP transport.

Ask your agent:

  • "What are prediction markets saying about Iran right now?"
  • "Is there a divergence between BTC perp traders and prediction markets?"
  • "What markets moved the most in the last 24 hours?"
  • "Are any whales active on both Hyperliquid and Polymarket for BTC right now?"

Early access

We're in an open early-access phase: all 44 tools, no gating, no credit card. The first 50 signups stay grandfathered for 90 days when paid plans launch.

Self-host

The public OSS core covers the read-only data layer (Polymarket + Hyperliquid wrappers, MCP server, signup/auth). The intelligence/private tools (signals, conviction scores, macro flow) live in a private side module — the hosted version exposes them, the OSS one doesn't.

bash
git clone https://github.com/RavioleLabs/predmcpcd predmcpnpm installnpm run buildIP_HASH_PEPPER="$(openssl rand -hex 32)" npm start

Server runs on http://localhost:3000/mcp. Public data sources require no upstream API keys.

Returns top of book, spread, cumulative depth at $100/$500/$1k/$5k tiers, and estimated slippage for a given order size. Critical for HIP-4 farming and low-liquidity assets where market orders get destroyed by slippage.

Parameterscoinrequiredsidesize_usdc

get_price_summary

Get Price Summary

One-call snapshot for an asset: mark price, 24h and 7d returns, 30d high/low, drawdown from high, rally from low, annualized realised volatility. Computed from 30d of HL hourly candles.

Parametersassetrequired

get_basic_macro

Get Basic Macro

DXY, US10Y yield, S&P 500, gold, VIX — direct from free Yahoo Finance. Raw values + 1d change. Pro adds BTC dominance, ETH/BTC, total crypto mcap, and a RISK_ON/OFF regime classifier.

Takes no parameters.

get_recent_news

Get Recent News

Recent crypto news headlines matching an asset ticker, from CoinDesk + The Block + Decrypt + Cointelegraph RSS feeds. Pro adds the 1h price move that followed each headline.

Parametersassetrequiredlimithours_back

get_news_feed

Get News Feed

Recent headlines across crypto, finance and sports RSS feeds, unfiltered and unclassified. Unlike get_recent_news it does not filter by asset ticker, so it also covers the sports, macro and event markets that make up most of a HIP-4 board. Match the headlines against your own market list.

Parameterslimitcategoryhours_back

get_simple_iv

Get Simple IV

BTC or ETH options snapshot via free Deribit public feed: ATM implied volatility, total OI, 24h volume. Pro adds put-call skew + full term structure parsing.

Parametersassetrequired

get_outcome_fair_value

Get Outcome Fair Value

Options/vol-implied fair value for a HIP-4 binary/range/touch PRICE market ("<asset> above $X at time T?"). Returns the risk-neutral probability the market resolves YES, and — if you pass market_yes_price — the signed edge in probability points and a YES cheap/rich/fair verdict. BTC/ETH price off the live Deribit IV smile (interpolated to strike + DTE); ANY other asset falls back to Hyperliquid 30d realized vol. iv_source labels which was used (smile/term_interp/skew_adj/atm/realized_vol). The touch case uses the correct drifted first-passage formula. Approximations are listed in caveats.

Parametersassetrequiredstrikerequiredcomparatorrequiredexpiry_isorequiredstrike_highmarket_yes_price

get_outcome_edges

Get Outcome Edges

One-call mispricing scanner for autonomous agents: every live HIP-4 PRICE market, each priced against its options/vol-implied fair value and ranked by |edge|. BTC/ETH use the Deribit IV smile; other assets use Hyperliquid realized vol (iv_source labels which). edge_pt = (implied_prob - yes_price)*100, computed only where a real traded YES price exists (synthetic/untraded 0.5 placeholders return edge_pt:null so no fake edge is surfaced). Filter with min_edge_pt / underlying. The whole board without looping.

Parameterslimitunderlyingmin_edge_pt

get_market_edge

Get Market Edge

Universal fair-value anchor for ONE market of ANY category. Pass the question (+ optional strike/comparator/expiry/underlying for price markets, + yes_price). Dispatches to the best anchor: options/vol fair value (crypto price), a confident Polymarket twin (events/politics/sports), or a soft news lean. Returns { method, confidence, anchor_prob, hip4_yes, edge_pt, verdict, source_ref, note }. edge_pt = (anchor_prob - hip4_yes)*100; positive = YES cheap; null for untraded/synthetic prices.

Parametersstrikevol_24hquestionrequiredis_tradedyes_pricecomparatorexpiry_isounderlyingstrike_high

get_market_edges

Get Market Edges

One-call universal mispricing scanner across ALL HIP-4 market types (crypto price, sports, politics, macro, events). Resolves every market to its best anchor (options / Polymarket twin / news lean / none) and ranks by |edge|. Filter with method / min_edge_pt / limit. Returns by_method counts + ranked markets. Superset of get_outcome_edges.

Parameterslimitmethodmin_edge_pt

get_news_signals

Get News Signals

News → markets recommender: pulls recent crypto headlines, classifies each event type (depeg/hack_exploit/listing/delisting/unlock/regulatory/partnership/outage/hype/fud/macro), extracts the assets, maps to affected HIP-4 markets, and assigns a directional lean (YES up / YES down). Heuristic, low/medium confidence, NOT financial advice; war/hard-politics excluded. Powers a live "event → affected markets → lean" feed. Filter with hours / event_type / min_confidence / limit.

Parametershourslimitevent_typemin_confidence

get_recent_signals

Get Recent Signals

Server-detected events from the last hour: funding outliers (≥3x 7d baseline), whale trades (≥$100k), OI caps reached. Cursor-based — pass next_cursor back as since_id to receive only new events. The polling equivalent of the /sse/signals stream. Pro tool get_signal_history covers 7 days with forward-return outcomes.

Parameterscoinlimitsince_id

get_oi_history

Get OI History

Open-interest time series for a coin over the last 24h, from our continuous 5-min collector. Hyperliquid has NO OI-history endpoint — this data exists only on predmcp. Includes price + funding at each point. Pro tool get_oi_divergence classifies price-vs-OI regimes (squeeze/liquidation/new positioning) across all coins.

Parameterscoinrequiredhours

get_market_regime

Get Market Regime

One-call market regime classifier: RISK_ON_TRENDING / RISK_OFF / SQUEEZE_RISK / CHOP_LOW_VOL / MIXED. Combines BTC trend + realized vol, Deribit IV premium, funding breadth, and OI-weighted crowding across the top 50 perps. Call this FIRST each session to condition strategy choice.

Takes no parameters.

get_market_context

Get Market Context

Unified intelligence snapshot for any topic, asset, or keyword: all matching Polymarket and HIP-4 prediction markets combined with live Hyperliquid perp data (price, funding, OI). One call replaces 3+ separate lookups.

Parametersqueryrequired

get_pm_hl_divergences

Get PM/HL Divergences

Markets where Polymarket implied probability diverges from Hyperliquid perpetual funding direction — e.g. PM prices bullish outcome but HL funding shows crowded longs (bearish pressure). The hardest signal to compute manually.

Parameterslimitmin_pct

get_hip4_vs_pm_arb

Get HIP-4 vs PM Arb

Finds the same underlying market priced on both HIP-4 (on-chain Hyperliquid) and Polymarket, flagging spreads above threshold. A spread means one venue is mispriced relative to the other.

Parametersmin_spread_pct

get_funding_outliers

Get Funding Outliers

Hyperliquid perps whose current funding rate deviates significantly from their 7-day average. A spike vs baseline is a stronger signal than raw rate.

Parametersdaysmin_deviation_factor

get_liquidation_clusters

Get Liquidation Clusters

Estimated price levels where mass liquidations concentrate for a given Hyperliquid perp, computed from mark price and standard leverage multiples. Higher nearby orderbook liquidity = stronger support/resistance.

Parameterscoinrequired

get_signal_backtest

Get Signal Backtest

Find historical instances of a signal type on an asset over the last N days and compute forward returns (1h/4h/24h), win rate, and Sharpe. Lets an agent reason about EV before trading. Killer feature: turns predmcp from data API into edge-proven intelligence.

Parametersassetrequiredz_scoresignal_typerequiredmin_abs_ratelookback_daysmin_separation_hours

get_conviction_score

Get Conviction Score

Aggregates funding outlier, whale imbalance, OI/volume ratio, and momentum into a single directional score (-100 short ↔ +100 long) plus a 0-100 strength score. One call replaces 6+ lookups, returns a clean number for LLM decisions.

Parametersassetrequiredwhale_window_minutesmin_whale_notional_usdc

get_funding_curve_anomaly

Get Funding Curve Anomaly

Term-structure analysis of Hyperliquid funding for an asset: current vs 8h avg vs 24h avg vs 7d baseline. Flags spikes, regime shifts, sign contradictions. More nuanced than raw funding rate.

Parametersassetrequired

get_setup_quality

Get Setup Quality

Execution-quality score (0-100, A-F grade) for entering a position right now: spread, slippage at desired size, orderbook depth, volatility regime, trend alignment, support/resistance proximity. Different from conviction (direction) — this scores ENTRY conditions.

Parametersassetrequireddirectionrequiredsize_usdc

get_upcoming_catalysts

Get Upcoming Catalysts

Lists upcoming market catalysts for an asset within a horizon: token unlocks, governance votes (Tally), ETF/SEC deadlines, FOMC dates. Helps agents avoid blind trades into known events. Free data sources (Tally + curated DB).

Parametersassetrequiredhorizon_hours

get_macro_context

Get Macro Context

Live macro snapshot: DXY, US10Y yield, S&P 500, gold, VIX (Yahoo Finance free) + BTC dominance, ETH/BTC, total crypto market cap (CoinGecko free). Plus a coarse RISK_ON / RISK_OFF / MIXED regime.

Takes no parameters.

get_macro_liquidity

Get Macro Liquidity

Fiat-to-crypto liquidity gauge: BTC + ETH spot ETF flows (Farside) plus on-chain USDT + USDC mint/burn (Etherscan). Net inflow = bullish for risk assets.

Takes no parameters.

get_cex_outflows

Get CEX Outflows

Net ETH outflows across known CEX hot wallets (Binance, Coinbase, OKX, Kraken, Bitfinex) over a window. Outflow = bullish (BTC moving to cold storage). Inflow = distribution pressure. Etherscan free tier.

Parametersexchangewindow_hours

get_news_correlation

Get News Correlation

Recent crypto news headlines mentioning an asset (CoinDesk, The Block, Decrypt, Cointelegraph) paired with the 1h price move that followed each. Lets agents filter news bias.

Parametersassetrequiredhours_back

get_portfolio_risk

Get Portfolio Risk

Risk analytics for a list of positions: per-position beta to BTC and ETH, sector concentration, pairwise correlation matrix, portfolio annualized volatility, 1-day 95% parametric VaR. Uses 14d of 1h Hyperliquid candles.

Parameterspositionsrequired

get_options_iv

Get Options IV

BTC or ETH options snapshot via free Deribit feed: ATM implied volatility, put-call skew, term structure, total OI and 24h volume. Useful as a sentiment gauge — IV high = market expects big moves; skew indicates direction of hedging.

Parametersassetrequired

get_whale_label

Get Whale Label

Look up an Ethereum address against our curated label DB (CEX hot wallets, known market makers, suspected funds). Lets agents distinguish mechanical MM flow from alpha-generating activity.

Parametersaddressrequired

get_signal_history

Get Signal History

Server-detected signal events over up to 7 days (funding outliers, whale trades ≥$100k, OI caps), each joined with its measured forward returns (1h/4h/24h) once mature. Cursor-based. "What happened last time funding spiked on HYPE — and did it matter?" in one call.

Parameterscoinlimitsince_idhours_backsignal_types

get_signal_performance

Get Signal Performance

Hit rates and average forward returns per signal type, measured on OUR actually-emitted production signals (not a backtest reconstruction). Use this to ground win_rate inputs for get_position_size. Sample sizes included — treat n < 10 as anecdotal.

Parameterscoindayssignal_type

get_oi_divergence

Get OI Divergence

Price-vs-OI regime per coin from our continuous snapshots: NEW_LONGS / SHORT_SQUEEZE / NEW_SHORTS / LONG_LIQUIDATION. Scan all tracked coins or analyze one. Impossible without OI history, which no public API provides — only predmcp records it.

Parameterscoinhours

get_whale_flow

Get Whale Flow

Cumulative whale buy/sell imbalance over hours-to-days from the durable trade tape (≥$25k trades persisted continuously, restart-proof). Returns imbalance ratio (-1..+1), BUY/SELL_DOMINANT verdict, and the largest recent prints. Longer horizons than get_whale_trades (1h buffer).

Parameterscoinrequiredhoursmin_notional_usdc

get_position_size

Get Position Size

Turn a signal + bankroll into a concrete position: fractional-Kelly size capped by orderbook liquidity, ATR-based stop, liquidation price at chosen leverage, funding carry cost, and % bankroll at risk. Warns when liquidation sits inside the stop. Ground win_rate_pct with get_signal_performance or get_signal_backtest first.

Parametersassetrequiredleveragedirectionrequiredpayoff_ratiowin_rate_pctbankroll_usdcrequiredkelly_fractionmax_slippage_pct

get_carry_scanner

Get Carry Scanner

Funding carry NET of costs: annualized funding minus (spread + 2x slippage at your size), with break-even holding period and a 7d funding-stability score from our snapshots. get_top_funding_rates shows gross — nobody trades gross.

Parameterstop_nsize_usdc

get_cross_venue_funding
