Trade on Kraken from your terminal, or let your AI agent trade for you. One install covers crypto, tokenized U.S. stocks and ETFs (for non-U.S. customers), forex, and futures. Every command can answer in JSON. A built-in MCP server connects the CLI to Claude, Cursor, Codex and other agents, and paper trading runs on live prices with no account.

[!TIP] New: sign in with OAuth. You no longer have to fumble around for API keys.
kraken auth loginopens Kraken in your browser, you approve, and the CLI saves a restricted Spot API key for you. The key can't withdraw funds, and it expires on its own. See how it works.
With kraken-cli you can:
kraken-mcp, which serves up to 152 MCP tools. On clients that support MCP
elicitation, calls that move money ask you first; the kraken CLI itself
places orders without a prompt. MCP server-o json, and a failure comes back as JSON
with a stable error field and a non-zero exit code.
For AI agents| You are | Start here |
|---|---|
| A person at a terminal | Install, then follow the Quick start from sign-in to your first order. |
| An AI agent, or building one | Read For AI agents and AGENTS.md. Ask your human to open a new terminal and run kraken auth login there, then call kraken <command> -o json 2>/dev/null. Orders trade real money with no confirmation prompt, so follow the rules for trading real money. |
| Just looking around | Market data and paper trading need no account. Try steps 1 and 2 of the Quick start. |
Paste one of these prompts into Claude Code, Codex, Cursor, or another AI coding agent. No agent yet? Install Claude Code first.

One install, no runtime dependencies. It puts three binaries on your PATH:
kraken, kraken-mcp (the MCP server) and kraken-shell (an interactive
shell).
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/krakenfx/kraken-cli/releases/latest/download/kraken-cli-installer.sh | sh
The installer detects your OS and architecture, downloads the right build, and installs it. macOS (Apple Silicon and Intel) and Linux (x86_64 and ARM64) are supported. On Windows, use WSL. AI agents: ask your human before you run the installer on their machine.
Open a new terminal (or run source "$HOME/.cargo/env"), then check that it
works:
kraken status && kraken ticker BTCUSD
[!NOTE]
command not found: krakenright after install? The installer puts the binaries in~/.cargo/bin(or$CARGO_HOME/binif you set it) and adds that folder to your PATH for new terminals only.
- AI agent in the middle of a task: call
~/.cargo/bin/kraken(or$CARGO_HOME/bin/kraken) by its full path for the rest of the session.- Terminal: open a new window, or run
source "$HOME/.cargo/env"($CARGO_HOME/envif you set it,env.fishfor fish).- Claude Code, Codex, or another agent you start in a terminal: quit it, open a new terminal window, and start it there. The old window keeps the old PATH.
- Cursor, VS Code, Claude Desktop, or another desktop app: quit it and open it again. If it still can't find
kraken, use the full path thatcommand -v krakenprints in a new terminal.
Pre-built binaries are also on the GitHub Releases page.
Releases are signed with minisign. Every
release archive, its .sha256 file, the installer script and SHA256SUMS.txt
on the Releases page has a
matching .minisig signature file.
Download the archive and its .minisig into the same folder, then check it
against the public key:
minisign -Vm kraken-cli-aarch64-apple-darwin.tar.gz -P RWQJue8SwPzZBZO8Up5ppAUqm0wM/gK5yjnam+Dbf7KbY0utkiO+7XCd
Public key:
RWQJue8SwPzZBZO8Up5ppAUqm0wM/gK5yjnam+Dbf7KbY0utkiO+7XCd
Install minisign with brew install minisign (macOS) or apt install minisign
(Linux). To check the installer before you run it:
curl -LO https://github.com/krakenfx/kraken-cli/releases/latest/download/kraken-cli-installer.sh
curl -LO https://github.com/krakenfx/kraken-cli/releases/latest/download/kraken-cli-installer.sh.minisig
minisign -Vm kraken-cli-installer.sh -P RWQJue8SwPzZBZO8Up5ppAUqm0wM/gK5yjnam+Dbf7KbY0utkiO+7XCd && sh kraken-cli-installer.sh
Requires Rust 1.97 or later. If cargo says a newer rustc
is required, run rustup update. A clone pins its toolchain in
rust-toolchain.toml, so rustup may download that version on the first build.
A source build is DuckDB-free by default, because the bundled DuckDB C++ build
dominates compile time and only DuckDB tapes need it: writing one
(kraken record --to duckdb) or reading one, such as a 0.4.x tape. Pass
--features record-duckdb to any command below to include it; the released
binaries already carry it.
Both commands install all three binaries: kraken, kraken-mcp and
kraken-shell.
