## What it does

Vulcan connects Claude Code to the Phoenix decentralized exchange through a local MCP server. It exposes market tickers and margin metrics to the agent.

A built-in paper trading engine runs against live orderbooks without touching real funds. Real trading requires the `--dangerous` flag during setup alongside explicit `acknowledged: true` confirmations for every order.

Enabling real trades stores your unlocked wallet password in the local MCP configuration file with `chmod 0600` permissions.

# Vulcan

Agent and human-friendly CLI for trading perpetual futures on [Phoenix](https://phoenix.trade).

> ⚠️ **Experimental software:** live commands can execute irreversible financial transactions on Solana Mainnet. You are responsible for wallet security, agent permissions, and all trading outcomes.

## What Vulcan Provides

- Account, margin, position, and order management for Phoenix perps.
- Local paper trading with live market prices and no wallet required.
- A local MCP server so agents can use Vulcan tools directly.
- First-class strategy runners for TWAP, grid trading, and TA.
- Bundled Agent Skills for Cursor, Claude Code, Codex, and Agentskills/OpenClaw-style clients.

### Example Agent Prompts

> "Give me a full portfolio snapshot: cross + isolated margin health, open positions with unrealized PnL %, resting orders, and any funding exposure I should know about."
>
> "Scan the top 5 markets on Phoenix by 24h volume — give me funding rate, mark price, and a one-line take on each."
>
> "Open a $200 long on SOL then attach a TP at +5% and SL at -3%."
>
> "I need to long $5,000 of SOL. Run a TWAP over 20 minutes in 10 slices.
>
> "Watch BTC on 15m and alert me when EMA(9) crosses EMA(21), paper only"
>
> "Build a TA strategy that goes long when RSI(14) crosses above 30 on the 5m and exits when it crosses 70. Paper mode first, $500 per entry"

## Install

Install the latest release on macOS/Linux:

```bash
curl -fsSL https://github.com/Ellipsis-Labs/vulcan-cli/releases/latest/download/install.sh | sh
```

The installer verifies the release archive against `vulcan-checksums-sha256.txt` and installs to `~/.local/bin/vulcan` by default. Make sure `~/.local/bin` is on your `PATH`.

Install a specific version:

```bash
curl -fsSL https://github.com/Ellipsis-Labs/vulcan-cli/releases/download/v0.5.3/install.sh | sh
```

Build from source:

```bash
cargo install --path vulcan
```

Verify:

```bash
vulcan version
```

Check for newer releases:

```bash
vulcan update check
```

This is read-only — vulcan never modifies its own binary. When an update is available it prints a method-appropriate hint: re-run the install one-liner above for default or custom `~/.local/bin`-style installs, or use your package manager for Homebrew/Nix/distro installs. Agents that load `vulcan://agent/health` see the same information under `cli_update`.

## Quick Start

```bash
# Guided setup for config, wallet, registration, deposit, and agent options
vulcan setup

# Check installation, config, wallet, RPC/API, registration, and paper readiness
vulcan status -o json

# Read market data
vulcan market list -o json
vulcan market ticker SOL -o json

# Begin paper trading
vulcan paper init --balance 10000 -o json
vulcan paper buy SOL --notional-usdc 100 --type market -o json
vulcan paper status -o json
```

## Agent Setup

Vulcan installs a local MCP server and a bundled set of Agent Skills into your agent host (Claude Code, Cursor, Codex, or any agentskills-compatible client). Two commands per host: one to install the skill files, one to register the MCP server. Live trading is opt-in.

Supported `--target` values: `claude`, `cursor`, `codex`, `agentskills`. `--scope user` writes to your user-level config (default); `--scope project` writes to the current project.

### Step 1: Install skills + MCP server (read-only / paper-safe)

```bash
# Bundled Agent Skills (workflow guides, recipes, runtime contract)
vulcan agent install --target claude --scope user

# Register the Vulcan MCP server with the host's standard config file
vulcan agent mcp install --target claude --scope user

# End-to-end probe: spawn the server, handshake, assert vulcan_* tools appear
vulcan agent mcp diagnose --target claude --scope user
```

**Fully restart your host** afterward so it picks up the new MCP server.

### Step 2 (optional): Enable live trading

Live trading requires a stored wallet to unlock for signing and live signing permission. You can setup at install time with `--dangerous`

```bash
# Wire up the wallet for live signing.
