Overview

AI-generated overview

Remote MCP server exposing Curade's paid Polymarket odds, cross-venue disagreement, market data packages and Hyperliquid perp funding, billed per call in USDC.

What you can do
  • Fetch volume-ranked Polymarket odds snapshots with implied probabilities, 24h volume and liquidity, optionally filtered by question.
  • Compare Polymarket and Kalshi implied probabilities for matched questions and see per-pair gaps and maximum disagreement.
  • Buy a one-time attested data package for a single market, including all snapshot rows, provenance and a signed license token.
  • Read the latest Hyperliquid perpetual funding rates per coin with derived APR, ranked by open interest.
When to use it
Useful when an assistant needs current prediction-market pricing, a second venue's view before acting on a Polymarket signal, a complete auditable record of one market for backtesting, or perp funding rates for a carry or basis view.
Requirements
A remote streamable-http endpoint; no local install or account. Every tool call is paid per call in USDC on Base mainnet via x402, so the client needs an x402-capable wallet or SDK that can answer the payment challenge and retry with a Payment-Signature header. Network access to the endpoint is required.
Before you install
Calls cost money: about $0.005 for odds, $0.02 for disagreement, $0.001 for funding and $2.00 for a market package, so automated retries can spend funds. Payment requires signing an EIP-3009 authorization with a wallet, and the challenge names a payTo address and facilitator to trust. The server itself holds no keys and settles nothing.

Installation

In SourceWeft

  1. Open Curade — prediction-market & perp-funding data (x402) in the dashboard and add it to a workspace.
  2. 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.sryantrabot%2Fcurade-mcp/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

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

sh
# 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).

Tools

curade_polymarket_odds

Normalized Polymarket odds snapshot: volume-ranked rows with question, yes/no prices, 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 specific question. Refreshed every collector batch. Source: Polymarket public data (derived, attributed). Paid via x402 (USDC on Base): $0.005 per call. [Payment: $0.005 per call. Unpaid calls return the x402 challenge; pay it and retry.]

Parametersqlimit

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 mispricings. Refreshed every collector batch. Sources: Polymarket + Kalshi public data (derived, attributed). Paid via x402 (USDC on Base): $0.02 per call. [Payment: $0.02 per call. Unpaid calls return the x402 challenge; pay it and retry.]

Takes no parameters.

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. Source: Polymarket public data (derived, attributed). Paid via x402 (USDC on Base): $2.00 flat. [Payment: $2.00 one-time. Unpaid calls return the x402 challenge; pay it and retry.]

Parametersmarketrequired

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: Hyperliquid public data (derived, attributed). Paid via x402 (USDC on Base): $0.001 per call. [Payment: $0.001 per call. Unpaid calls return the x402 challenge; pay it and retry.]
