What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • curade_polymarket_odds

    Normalized Polymarket odds snapshot: volume-ranked rows with question, YES/NO probability, implied probability, 24h volume and liquidity. Use when an agent needs current prediction-market pricing: check whether a market moved after news, rank the busiest markets, or scan for a sp

  • curade_polymarket_disagreement

    Cross-venue disagreement for prediction markets: Polymarket vs Kalshi implied probabilities for matched questions, per-pair gap and the max disagreement. Use when an agent needs a second opinion on a market's pricing before acting on a Polymarket signal, or to detect cross-venue

  • curade_polymarket_package

    One-time purchase, keep the data: full attested Polymarket data package for ONE market (all snapshot rows, provenance and a signed license token). Use when an agent needs the complete record for one market rather than a live snapshot, e.g. for backtesting or an audit trail. Sourc

  • curade_hyperliquid_funding

    Latest Hyperliquid perpetual-funding snapshot (up to 100 coins ranked by open interest): hourly funding rate per coin (signed; positive = longs pay shorts) and derived APR. Use when an agent needs current perp funding rates for a carry or basis view. Updated hourly. Source: Hyper

Common questions

Is Curade — prediction-market & perp-funding data (x402) safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Souvenir, XRPLME Country Intelligence, Crypto News Sentiment (x402)

curade-mcp

A remote MCP (Model Context Protocol) server that exposes Curade's paid data API (https://api.curade.xyz) as four MCP tools over the official streamable-http transport:

ToolWhat it returnsPrice
curade_polymarket_oddsNormalized Polymarket odds snapshot (volume-ranked rows, question filter)$0.005/call
curade_polymarket_disagreementPolymarket vs Kalshi cross-venue disagreement per question$0.02/call
curade_polymarket_packageFull attested data package for one market + signed license (one-time)$2.00
curade_hyperliquid_fundingLatest Hyperliquid per-coin funding rates + APR$0.001/call

Live endpoint: https://curade.xyz/mcp (POST, JSON-RPC 2.0, MCP protocol 2025-06-18)

How payment works (x402)

Every tool call is paid per call with the x402 protocol (USDC on Base mainnet, scheme exact). This server holds no keys and settles nothing:

  1. Call any tool with no payment header.
  2. The call returns an MCP error result whose text contains the decoded x402 challenge (from the upstream 402 response): amount, payTo address, network, facilitator.
  3. Your client pays per the challenge (EIP-3009 transferWithAuthorization, settled via the facilitator named in the challenge) and retries the same call with a Payment-Signature header.
  4. x402-aware clients (SDKs from x402) do this automatically.

Data source: Polymarket's public data and Hyperliquid's public funding archive; outputs are derived and attributed ("source: Polymarket" / "source: Hyperliquid").

Try it

# 1. initialize + tools/list (free, no payment)

curl -s -X POST https://curade.xyz/mcp -H 'content-type: application/json' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

An unpaid tools/call returns the challenge; pay and retry to get data.

Deploy / develop

The server is a single zero-dependency JavaScript module (mcp.js at this repo root, mirrored into the curade site deploy) served as a serverless function behind https://curade.xyz/mcp. No state, no session store: stateless streamable-http (you may pass Mcp-Session-Id; it is echoed, not stored).

Maintained by sryantrabot (the Curade org, an automated agent org).
