Kraken CLI

version license platform

The first AI-native CLI for trading crypto, stocks, forex, and derivatives.

Full Kraken API access. Built-in MCP server. Live and paper trading. Single binary.

Works with Cursor, Claude, Codex, Copilot, Gemini, Goose, and OpenClaw.

Try these with your AI agent:

"Install kraken-cli (https://github.com/krakenfx/kraken-cli) and build me a morning market brief."

"Watch ETH, SOL, and BTC for 30 seconds. What are the pros and cons of buying each right now?"

"Look up AAPLx, TSLAx, and SPYx on xStocks. Summarize how each is performing today."

"You are a Wall Street veteran with 20 years of experience. You have 1 minute. Paper trade BTC and show me your P&L."


Caution

Experimental software. Interacts with the live Kraken exchange and can execute real financial transactions. Read DISCLAIMER.md before using with real funds or AI agents.

Contents

Installation

Single binary, no runtime dependencies.

One-liner

curl --proto '=https' --tlsv1.2 -LsSf https://github.com/krakenfx/kraken-cli/releases/latest/download/kraken-cli-installer.sh | sh

For AI Agents

If you're an AI agent or building one, start here:

Resource Description
CONTEXT.md Runtime context for tool-using agents
AGENTS.md Full integration guide: auth, invocation, errors, rate limits
agents/tool-catalog.json 134 commands with parameter schemas, types, and safety flags
agents/error-catalog.json 9 error categories with retry guidance
skills/ 50 goal-oriented SKILL.md workflow packages
CLAUDE.md Claude-specific integration guidance

Core invocation pattern:

kraken <command> [args...] -o json 2>/dev/null
  • stdout is always valid JSON on success, or a JSON error envelope on failure.
  • Exit code 0 means success. Non-zero means failure.
  • stderr carries diagnostics only (enabled with -v). Never parse stderr for data.
Why Agent-First?

Most CLIs are built for humans at a terminal. This one is built for LLM-based agents, MCP tool servers, and automated pipelines that need to call Kraken reliably without custom API clients.

  • Structured output by default. Every command supports -o json. No screen-scraping, no regex on table borders.
  • Consistent error envelopes. Errors are JSON objects with a stable error field (auth, rate_limit, validation, api, network). Agents route on error without parsing human sentences.
  • Predictable exit codes. Success is 0, failure is non-zero. Combined with JSON errors on stdout, agents detect and classify failures programmatically.
  • Paper trading for safe iteration. Test strategies against live prices with kraken paper commands. No API keys, no real money, same interface.
  • Full API surface. 134 commands covering Spot, Futures, xStocks, Forex, Funding, Earn, Subaccounts, and WebSocket streaming.
  • Built-in MCP server. Native Model Context Protocol support over stdio. No subprocess wrappers needed.
  • Rate-limit aware. No client-side throttling. When the Kraken API rejects a request due to rate limits, the CLI returns an enriched error with suggestion, retryable, and docs_url fields so agents can read the documentation and adapt their strategy.

Humans benefit from the same design: --output table renders clean tables, kraken shell provides a REPL, and kraken setup walks through configuration.

Verifying Binaries

Release binaries are signed with minisign. Every artifact on the Releases page has a corresponding .minisig signature file.

Public key:

RWQJue8SwPzZBZO8Up5ppAUqm0wM/gK5yjnam+Dbf7KbY0utkiO+7XCd

Verify a downloaded binary:

minisign -Vm kraken-cli-aarch64-apple-darwin.tar.gz -P RWQJue8SwPzZBZO8Up5ppAUqm0wM/gK5yjnam+Dbf7KbY0utkiO+7XCd

Install minisign: brew install minisign (macOS) or apt install minisign (Linux).

Quick Start

Public market data requires no credentials:

kraken ticker BTCUSD -o json
kraken orderbook BTCUSD --count 10 -o json
kraken trades BTCUSD --count 20 -o json
kraken ohlc BTCUSD --interval 60 -o json

With authentication:

export KRAKEN_API_KEY="your-key"
export KRAKEN_API_SECRET="your-secret"

kraken balance -o json
kraken open-orders -o json
kraken order buy BTCUSD 0.001 --type limit --price 50000 -o json

For humans (table output, interactive setup):

kraken setup
kraken ticker BTCUSD
kraken balance
kraken shell

API Keys & Configuration

Authenticated commands (trading, balances, order management) require a Kraken API key pair. Public market data and paper trading work without credentials.

Getting API keys

Spot (covers trading, balances, funding, earn, subaccounts): Settings > API on kraken.com. Full guide: How to create a spot API key.

Futures (only for kraken futures commands): Settings > Create Key on the Futures interface. Full guide: How to create a Futures API key.

Grant the minimum permissions your workflow needs. For read-only monitoring, "Query Funds" and "Query Open Orders & Trades" are sufficient.

Environment variables (recommended for agents)

export KRAKEN_API_KEY="your-key"
export KRAKEN_API_SECRET="your-secret"
export KRAKEN_FUTURES_API_KEY="your-futures-key"       # optional
export KRAKEN_FUTURES_API_SECRET="your-futures-secret"  # optional

Config file (for humans)

Store credentials in ~/.config/kraken/config.toml:

[auth]
api_key = "your-api-key"
api_secret = "your-api-secret"

[settings]
default_pair = "BTCUSD"
output = "table"

Or use the interactive wizard: kraken setup.

Credential resolution

Highest precedence first:

  1. Command-line flags (--api-key, --api-secret)
  2. Environment variables (KRAKEN_API_KEY, KRAKEN_API_SECRET)
  3. Config file (~/.config/kraken/config.toml)

Security

  • Config file is created with 0600 permissions (owner read/write only)
  • Secrets are never logged, printed, or included in error messages
  • Use --api-secret-stdin or --api-secret-file instead of --api-secret to avoid secrets in process listings
  • For automation, prefer environment variables over command-line flags
Advanced: API endpoint overrides
Variable Default Description
KRAKEN_SPOT_URL https://api.kraken.com Spot REST API base URL
KRAKEN_FUTURES_URL https://futures.kraken.com/derivatives/api/v3 Futures REST API base URL
KRAKEN_WS_PUBLIC_URL wss://ws.kraken.com/v2 Public WebSocket endpoint
KRAKEN_WS_AUTH_URL wss://ws-auth.kraken.com/v2 Authenticated Spot WebSocket endpoint
KRAKEN_WS_L3_URL wss://ws-l3.kraken.com/v2 Level 3 order book WebSocket endpoint
KRAKEN_FUTURES_WS_URL wss://futures.kraken.com/ws/v1 Futures WebSocket endpoint

Resolution: CLI flag > environment variable > default. Only https:// and wss:// schemes are accepted.

MCP Server

kraken-cli includes a built-in Model Context Protocol server over stdio. No subprocess wrappers needed.

MCP tool calls run through the same command path as CLI commands and inherit the same error handling and rate-limit behavior.

Warning

MCP is local-first and designed for your own machine. Any agent connected to this MCP server uses the same configured Kraken account and API key permissions. Do not expose, tunnel, or share this server outside systems you control. Always use https:// and wss:// endpoints. Treat this integration as alpha and use least-privilege API keys.

kraken mcp                           # read-only (market, account, paper)
kraken mcp -s all                    # all services, dangerous calls require acknowledged=true
kraken mcp -s all --allow-dangerous  # all services, no per-call confirmation
kraken mcp -s market,trade,paper     # specific services

Configure your MCP client (Claude Desktop, ChatGPT, Codex, Gemini CLI, Cursor, VS Code, Windsurf, etc.):

{
  "mcpServers": {
    "kraken": {
      "command": "kraken",
      "args": ["mcp", "-s", "all"]
    }
  }
}

Gemini CLI users can install directly: gemini extensions install https://github.com/krakenfx/kraken-cli

Service groups

Service Auth Risk
market No None
account Yes Read-only
trade Yes Orders (dangerous)
funding Yes Withdrawals (dangerous)
earn Yes Staking (dangerous)
subaccount Yes Transfers (dangerous)
futures Mixed Orders (dangerous)
paper No None (simulation)
auth No Read-only

Default: market,account,paper. Streaming groups (websocket, futures-ws) are excluded in MCP v1.

Dangerous tools carry the destructive_hint annotation and include [DANGEROUS: requires human confirmation] in the description. In guarded mode (default), dangerous calls must include acknowledged=true. In autonomous mode (--allow-dangerous), this requirement is disabled.

Output & Errors

JSON (-o json)

The primary output format. Every command returns valid JSON on stdout.

kraken ticker BTCUSD -o json
# {"BTCUSD":{"a":["67234.10","1","1.000"],"b":["67234.00","1","1.000"],...}}

WebSocket commands emit NDJSON (one JSON object per line) for streaming.

Table (-o table)

Human-readable tables. Default when -o is not specified.

┌──────────┬──────────┬──────────┬──────────┬────────────┐
│ Pair     │ Ask      │ Bid      │ Last     │ Volume ... │
├──────────┼──────────┼──────────┼──────────┼────────────┤
│ BTCUSD   │ 67234.10 │ 67234.00 │ 67234.10 │ 1234.56    │
└──────────┴──────────┴──────────┴──────────┴────────────┘

Error envelopes

On failure, stdout contains a JSON envelope with a stable error category:

{"error": "auth", "message": "Authentication failed: EAPI:Invalid key"}

Route on error, not on message. The message field is human-readable and not stable.

Category Retryable Action
auth No Check API key and secret
rate_limit Yes Error includes suggestion with tier-specific limits, docs_url pointing to Kraken documentation, and retryable flag. Read suggestion and adapt strategy.
network Yes Exponential backoff, max 5 retries
validation No Fix input parameters
api No Inspect request and parameters
config No Check config file or env vars
websocket Yes Reconnect with paced backoff and safety budget (up to 12 reconnect attempts per stream lifecycle)
io No Check file paths and permissions
parse No Log raw response, possible API maintenance

Full error catalog with envelopes and backoff strategies: agents/error-catalog.json.

Verbose (-v)

Request/response diagnostics go to stderr, keeping stdout clean:

kraken balance -o json -v 2>/dev/null | jq .

Commands

134 commands across 12 groups. For machine-readable parameter schemas, load agents/tool-catalog.json.

Group Commands Auth Description
market 10 No Ticker, orderbook, OHLC, trades, spreads, asset info
account 18 Yes Balances, orders, trades, ledgers, positions, exports
trade 9 Yes Order placement, amendment, cancellation (spot, xStocks, forex)

Paper Trading

Paper trading provides a safe sandbox for testing trading logic against live Kraken prices. No API keys, no account, no real money. The command interface mirrors live trading exactly; agents can switch between paper and live by changing the command prefix (kraken paper buy vs kraken order buy).

Agent pattern:

kraken paper init --balance 10000 -o json
kraken paper buy BTCUSD 0.01 -o json
kraken paper sell BTCUSD 0.005 --type limit --price 70000 -o json
kraken paper status -o json
kraken paper reset -o json

Human pattern:

kraken paper init --balance 5000 --currency EUR
kraken paper buy BTCUSD 0.01
kraken paper balance
kraken paper status
kraken paper orders
kraken paper history
kraken paper reset
Command Description
kraken paper init [--balance 10000] [--currency USD] Initialize paper account
kraken paper reset Reconcile pending orders, then reset
kraken paper balance All balances (total, reserved, available)
kraken paper buy <PAIR> <VOL> [--type limit --price P] Paper buy (market or limit)
kraken paper sell <PAIR> <VOL> [--type limit --price P] Paper sell (market or limit)
kraken paper orders Open limit orders
kraken paper cancel <ORDER_ID> Cancel a limit order
kraken paper cancel-all Cancel all limit orders
kraken paper history Filled trade history
kraken paper status Portfolio value, unrealized P&L, trade count

Prices come from the public Kraken Ticker API (no auth needed). A 0.26% taker fee (Kraken Starter tier default) is applied to all fills. Limit orders fill at the limit price when the live market crosses the order price.

All output is labeled [PAPER] in table mode and includes "mode": "paper" in JSON mode.

Examples

Conditional order based on live price

PRICE=$(kraken ticker BTCUSD -o json | jq -r '.[].c[0]')
kraken order buy BTCUSD 0.001 --type limit --price "$PRICE" -o json

Portfolio rebalance check

BTC=$(kraken balance -o json | jq -r '.BTC // "0"')

if [ "$(echo "$BTC > 0.001" | bc)" -eq 1 ]; then
  kraken order sell BTCUSD 0.001 --type market -o json
fi

Real-time price stream

kraken ws ticker BTC/USD -o json | while read -r line; do
  LAST=$(echo "$line" | jq -r '.data[0].last // empty')
  [ -n "$LAST" ] && echo "BTC: $LAST"
done

Stream multiple tickers

kraken ws ticker BTC/USD ETH/USD SOL/USD -o json

Dead man's switch

kraken order cancel-after 60

Cancels all open orders if the CLI does not reset the timer within 60 seconds.

Agent Skills

Ships with 50 agent skills covering trading strategies, market analysis, and portfolio management. See the full Skills Index.

Troubleshooting

macOS blocks the binary ("Apple could not verify")

xattr -d com.apple.quarantine /usr/local/bin/kraken

"EAPI:Invalid key" or authentication errors

Check that KRAKEN_API_KEY and KRAKEN_API_SECRET are set correctly. Keys are case-sensitive. Verify the API key has the required permissions for the command (Query Funds for balance, Modify Orders for order buy, etc.).

Rate limit errors

The CLI does not pre-throttle or retry rate-limited requests. The Kraken API server enforces rate limits, and the CLI returns the error immediately with a suggestion field containing tier-specific limits and a docs_url pointing to the relevant Kraken documentation. Read the suggestion and adjust request frequency. For sustained high-frequency use, prefer WebSocket streaming over REST polling.

"No tools found" in MCP client

Verify kraken is on your PATH. Run kraken mcp -s market in a terminal to confirm the server starts. Check that your client configuration matches the JSON format in the MCP Server section.

Paper trading state errors

Run kraken paper reset to clear and reinitialize.
