## Documentation

### Kraken Exchange

MCP server for the Kraken cryptocurrency exchange — 114 tools covering spot, futures, REST, and WebSocket APIs. Source: github.com/askbeka/tentactl (MIT license).

### How It Works

tentactl is a Rust binary that speaks MCP (Model Context Protocol) over stdio. It provides:

Spot REST (57 tools): Market data, account info, trading, funding, earn, subaccounts, exports
Futures REST (21 tools): Instruments, positions, orders, transfers, funding rates
Spot WebSocket v2 (19 tools): Live market data streams, real-time order management
Futures WebSocket (17 tools): Live futures feeds, real-time futures trading

### 1. Install the binary

cargo install tentactl

Or download from GitHub Releases (Linux, macOS, Windows).

### 2. Configure API keys (optional)

Market data tools work without any keys. For account and trading tools:

echo "KRAKEN_API_KEY=your-key" > ~/.tentactl.env
echo "KRAKEN_API_SECRET=your-secret" >> ~/.tentactl.env
chmod 600 ~/.tentactl.env

Or use the 1Password setup script: scripts/setup-keys.sh

Key permissions: Create keys at https://www.kraken.com/u/security/api

Read-only: enable Query Funds and Query Open Orders & Trades
Trading: also enable Create & Modify Orders

### Usage

# Market data (no auth)
scripts/kraken.sh get_ticker '{"pair":"XBTUSD"}'
scripts/kraken.sh get_orderbook '{"pair":"ETHUSD","count":5}'
scripts/kraken.sh futures_tickers '{}'

# Live WebSocket streams
scripts/kraken.sh ws_subscribe_ticker '{"symbols":["BTC/USD"]}'
scripts/kraken.sh ws_subscribe_book '{"symbols":["ETH/USD"],"depth":10}'
scripts/kraken.sh wf_subscribe_ticker '{"product_ids":["PI_XBTUSD"]}'
scripts/kraken.sh ws_status '{}'

# Account (needs API keys)
scripts/kraken.sh get_balance '{}'
scripts/kraken.sh futures_open_positions '{}'

# Trading (needs API keys) ⚠️ REAL MONEY
scripts/kraken.sh place_order '{"pair":"XBTUSD","direction":"buy","order_type":"limit","volume":"0.001","price":"50000","validate":true}'
scripts/kraken.sh ws_add_order '{"symbol":"BTC/USD","side":"buy","order_type":"limit","limit_price":"50000","order_qty":"0.001","validate":true}'

### Tools Reference

See references/tools.md for full parameter docs on all 114 tools.

### Safety Rules

ALWAYS use validate: true first when placing orders
ALWAYS confirm with the user before placing real orders
NEVER place orders without explicit user approval
Market orders execute IMMEDIATELY — prefer limit orders
Display validation result and ask for confirmation before removing validate
Trading tools are marked with ⚠️ REAL MONEY in their descriptions

### Trading Pairs

Spot REST: Kraken format — XBTUSD, ETHUSD, SOLUSD
Spot WebSocket: Standard format — BTC/USD, ETH/USD, SOL/USD
Futures: Product IDs — PI_XBTUSD, PI_ETHUSD, PF_SOLUSD

### DCA (Dollar Cost Average)

openclaw cron add --schedule "0 9 * * 1" --task "Buy $50 of BTC on Kraken using the kraken skill. Use validate first, then execute."

### Price Alerts

Subscribe to WebSocket ticker, check thresholds in heartbeat/cron, notify via WhatsApp/Telegram.

### Portfolio Monitoring

Cron job that checks balances + positions + current prices, calculates P&L, alerts on significant changes.

### Funding Rate Arbitrage

Subscribe to futures tickers, monitor funding rates, alert when rates diverge significantly.
