Overview

AI-generated overview

Remote MCP server that gives an assistant current and historical Hyperliquid perpetual funding rates and funding-rate arbitrage candidates.

What you can do
Fetch current funding rates for all 229 Hyperliquid perp markets, sorted by highest, lowest or absolute rate, with premium, open interest and mark price per coin. Retrieve historical funding rate entries for a chosen coin over a lookback window of up to 720 hours, with average, min, max and standard deviation. Scan all markets for funding-rate arbitrage candidates above a chosen threshold, flagged as long or short opportunities.
When to use it
Useful when checking the funding cost before opening a perpetual position, comparing carry-trade setups, gauging market sentiment, or screening Hyperliquid markets for extreme funding rates.
Requirements
A remote MCP endpoint reached over SSE; no API key, signup or environment variables. Each call is paid per use in USDC on Base L2 through the x402 protocol, so an x402-capable client with a funded wallet is needed to complete the payment challenge.
Before you install
Every tool call costs $0.002 in USDC on Base, so an assistant can spend real money from the connected wallet. Payment is handled by third-party facilitators (Coinbase CDP, PayAI), and the data comes from an external marketplace service. The output is market data, not investment advice.

Installation

In SourceWeft

  1. Open Hyperliquid Funding Rates API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. 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.Br0ski777%2Fhl-funding/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

Other MCP clients

Add this to your client's mcpServers config.

Hyperliquid Funding Rates API

[MCP Server] [x402] [License: MIT]

Real-time and historical Hyperliquid funding rates for 229 perp markets. Sort by highest/lowest, find arb opportunities. Zero-cost data. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "hl-funding": {      "url": "https://hl-funding.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl -X POST "https://hl-funding.api.klymax402.com/api/rates" \  -H "Content-Type: application/json" \  -d '{}'# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

hyperliquid_get_funding_rates

Use this when you need current funding rates across all Hyperliquid perpetual markets. Returns real-time funding rate, premium, open interest, and mark price for every listed perp coin on Hyperliquid DEX, sorted by your chosen criteria.

Parameters

NameTypeRequiredDescription
sortstringnoSort order for funding rates. 'highest' = most positive first (shorts pay longs), 'lowest' = most negative first (longs pay shorts), 'abs' = highest absolute value first (default).

Example response:

json
{ totalMarkets: 229, sort: "abs", rates: [{ coin: "BTC", fundingRate: 0.000125, annualizedRate: 13.69, premium: 0.0002, openInterest: 1250000000, markPrice: 68500.5 }, ...] }

When to use: opening perp positions to check funding cost. Essential for carry trade analysis, market sentiment gauging, and identifying crowded trades.

Not for: historical funding data (use hyperliquid_get_funding_history), vault performance data (use hyperliquid_get_vault_details), whale position tracking (use hyperliquid_track_whale_positions).

hyperliquid_get_funding_history

Use this when you need historical funding rate data for a specific Hyperliquid perpetual market. Returns timestamped funding rate entries over a configurable lookback window, plus summary statistics including average, min, max, and standard deviation.

Parameters

NameTypeRequiredDescription
coinstringyesCoin ticker symbol (e.g. BTC, ETH, SOL, DOGE). Must match a Hyperliquid perp market.
hoursnumbernoLookback window in hours. Default: 24. Max: 720 (30 days). Each funding period is 8 hours, so 24h returns ~3 entries.

Example response:

json
{ coin: "ETH", hours: 24, entries: [{ time: "2026-04-13T08:00:00Z", fundingRate: 0.0001, annualizedRate: 10.95 }, ...], summary: { count: 3, avgRate: 0.00012, avgAnnualized: 13.14, minRate: 0.00008, maxRate: 0.00015, stdDev: 0.000029 } }

Not for: current rates across all markets (use hyperliquid_get_funding_rates), CEX funding rates (use funding_rates_get_current).

hyperliquid_find_funding_arb

Use this when you need to find funding rate arbitrage opportunities on Hyperliquid. Scans all 229 perp markets and returns coins where the absolute funding rate exceeds 0.01% per 8h period (annualized > 36%), flagged as long or short opportunities based on rate direction.

Parameters

NameTypeRequiredDescription
thresholdnumbernoMinimum absolute funding rate to qualify as an arb opportunity. Default: 0.0001 (0.01% per 8h, ~36% annualized). Lower values return more results.

Example response:

json
{ threshold: 0.0001, totalOpportunities: 12, longOpportunities: 5, shortOpportunities: 7, opportunities: [{ coin: "PEPE", fundingRate: 0.0005, annualizedRate: 54.75, direction: "short opportunity", openInterest: 85000000, markPrice: 0.0000125, premium: 0.001 }, ...] }

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
