Instructions for using perp-cli, a command-line tool for perpetual futures trading across several decentralised exchanges. Perpetual futures are contracts that track an asset without a fixed expiry date.

Viewing markets, portfolios and positions, scanning funding-rate differences, analysing funding income, comparing arbitrage positions, and simulating or placing trades.

They standardise structured output, exchange selection and dry-run checks before trades are sent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00421	$0.00421
Opus 5.5	$0.00168	$0.00168
Sonnet 5.5	$0.00084	$0.00084
Haiku 4.5	$0.00042	$0.00042

Security

Grade A, and why

cursorrules scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You have access to perp-cli, a multi-DEX perpetual futures CLI trading on Hyperliquid (incl. HIP-3), Pacifica, Lighter, Lighter RH, Aster, Ondo Perps, Arcus, QFEX, RISEx and TxFlow (market data only: GRVT, Extended, Variational).

Usage

Always use --json flag for structured output
Always use --dry-run before executing trades
Use -e <exchange> to select exchange (e.g. hyperliquid, pacifica, lighter, lighter-rh, aster, ondo, arcus, qfex; aliases: hl, pac, lt, lrh, ast, qf) — perp --json lists every venue

Common Commands

perp --json portfolio                          # cross-exchange overview
perp --json -e hl market list                  # market data
perp --json -e hl account positions            # open positions
perp --json arb scan --min 5                   # funding rate arbitrage
perp --json --dry-run -e hl trade market ETH buy 0.1  # simulate trade
perp --json -e hl trade market ETH buy 0.1     # execute trade
perp --json analytics funding --period 30d     # funding income analysis
perp --json analytics compare                  # arb position comparison

MCP Server

perp-cli includes an MCP server (perp-mcp) with 31 tools for trading, analytics, and market data. Configure in Cursor settings:

{
  "mcpServers": {
    "perp-cli": {
      "command": "npx",
      "args": ["-y", "-p", "perp-cli", "perp-mcp"]
    }
  }
}

Safety

Never execute trades without user confirmation
Always preview with trade_preview before trade_execute
Use --dry-run for simulations

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
