@wezzcoetzee/hyperliquid-cli

A command-line trading executor for Hyperliquid perps, designed for agent use. Every command supports machine-readable output (--format json|yaml|toon|jsonl), JSON Schema introspection (--schema), an LLM manifest (--llms-full), and can run as a native MCP server (--mcp) so coding/trading agents can drive it directly.

What it can do

Account & state

• hl balance — Get perpetual account balance (account value, margin used, withdrawable, total notional)
• hl positions — List open positions (size, entry, leverage, unrealized PnL, liquidation price)
• hl orders — List open orders (resting limits, triggers, reduce-only flags)

Trading

• hl open <side> <size> <coin> — Open a position at market price (side = long | short)
• hl close <coin> [size] — Cancel all orders for the coin and close the position at market (reduce-only). Omit size for a full close.
• hl set-leverage <coin> <leverage> — Set leverage for a coin (cross margin)

Risk management

• hl stop-loss <side> <size> <coin> <triggerPrice> — Place a trigger stop-loss (reduce-only)
• hl take-profit <side> <size> <coin> <triggerPrice> — Place a trigger take-profit (reduce-only)
• hl move-sl <coin> <newPrice> — Cancel the existing stop-loss for a coin and replace it at a new trigger price
• hl cancel-all <coin> — Cancel every open order for a coin

Agent integration (built-in)

• --mcp — Run as an MCP stdio server; every command above becomes a tool
• hl mcp add — Register the CLI as an MCP server with your agent (Claude Code, Cursor, etc.)
• hl skills add — Sync skill files to your agent so it knows how to use the CLI
• --llms / --llms-full — Print an LLM-readable manifest of all commands
• --schema — Print the JSON Schema for any command's arguments and output
• completions — Generate a shell completion script

Install

npm install -g @wezzcoetzee/hyperliquid-cli

This installs the hl binary on your PATH. Requires Node.js 18+.

Setup

The CLI signs trades with your Hyperliquid wallet's private key, read from HYPERLIQUID_PRIVATE_KEY:

export HYPERLIQUID_PRIVATE_KEY=0x...

Or put it in a .env file in your working directory (a .env.example is in this repo for reference).

Security: This key can move funds. Never commit it, never paste it into shared shells, and prefer a dedicated Hyperliquid API wallet over your main account key.

Verify it's working:

hl balance

Quick start

hl balance
hl positions
hl open long 0.01 BTC
hl stop-loss long 0.01 BTC 60000
hl take-profit long 0.01 BTC 80000
hl close BTC

Using with an agent

Option 1 — Register as an MCP server (recommended)

Once installed globally, register hl with your agent. It exposes every command as a tool.

hl mcp add                          # auto-detects installed agents, registers globally
hl mcp add --agent claude-code      # target a specific agent
hl mcp add --no-global              # install to current project instead of globally

The agent will see tools like balance, positions, open, close, stop-loss, etc., each with full JSON Schema for arguments and outputs. Make sure HYPERLIQUID_PRIVATE_KEY is exported in the environment the agent launches MCP servers from.

To run the MCP server manually (for custom integrations):

hl --mcp

Option 2 — Shell out from the agent

Any agent that can run shell commands can use hl directly. Use --format json for parseable output:

hl positions --format json
hl balance --format json
hl open long 0.01 BTC --format json

For agents that need a compact menu of capabilities upfront, pipe hl --llms-full into the prompt — it's a complete machine-readable manifest of every command, argument, and output schema.

Option 3 — Sync skill files

hl skills add

Writes guidance files into your agent's skills directory so it knows when and how to call each command.

Output formats and filtering

Every command supports global flags:

| Flag | Description | | --- | --- | | --format <toon\|json\|yaml\|md\|jsonl> | Output format (default is human-readable) | | --filter-output <keys> | Filter response by key paths (e.g. --filter-output positions[0].coin,positions[0].szi) | | --verbose | Show full output envelope (timing, request id, etc.) | | --schema | Print JSON Schema for the command's input/output | | --token-count / --token-limit <n> / --token-offset <n> | Manage output size for LLM context windows | | --help | Show help for the command |

Run hl --help to see all globals, or hl <command> --help for a specific command.
