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:
Setup
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

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

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