What it does

Kraken MCP Integration is an agent skill from krakenfx/kraken-cli. Connect MCP clients to kraken-cli for native tool calling without subprocess wrappers.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: The first AI-native CLI for trading crypto, stocks, forex, and derivatives. The licence is MIT.

When your agent uses it

Tasks that involve MCP servers

Example prompts

“/kraken-mcp-integration”

Requirements

A credential in KRAKEN_API_KEY
A credential in KRAKEN_API_SECRET

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Configure your MCP client
Set credentials (only needed for live trading)
Restart your MCP client

What it can do on your machine

Read from SKILL.md and the folder at commit aa56e59. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- gemini
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- KRAKEN_API_KEY
- KRAKEN_API_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kraken MCP Integration loads about 1.5k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 645 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~27
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Connect MCP clients to kraken-cli for native tool calling without subprocess wrappers.
version: 1.0.0

kraken-mcp-integration

Use this skill to connect any MCP-compatible client to kraken-cli for structured tool calling over stdio.

MCP tool calls execute through the same command path as CLI commands, so error handling and rate-limit behavior is identical between MCP and CLI.

Supported Clients

Claude Desktop, ChatGPT, Codex, Gemini CLI, Cursor, VS Code, Windsurf, and any client that supports the MCP mcpServers configuration block.

Setup

1. Configure your MCP client

Add this to your MCP client configuration (Claude Desktop: claude_desktop_config.json, Cursor: .cursor/mcp.json, etc.):

json

{
  "mcpServers": {
    "kraken": {
      "command": "kraken",
      "args": ["mcp", "-s", "market,paper,feedback"]
    }
  }
}

-s market,paper,feedback is the default service list: public market data, paper trading, and the local feedback tool. No real funds can be touched until you opt in explicitly by expanding the service list. See Enabling live trading below.

Credential resolution follows the standard CLI precedence: command-line flags, then KRAKEN_API_KEY / KRAKEN_API_SECRET in the MCP server's env block, then a secure local config file managed by the CLI (written by kraken auth set and kraken setup, stored with user-only permissions in your OS's standard config directory). The MCP server and the standalone CLI share the same config file, so a single kraken auth set serves both.

2. Set credentials (only needed for live trading)

If you stay on market,paper,feedback, skip this step — paper trading needs no keys.

For live trading, the MCP server reads credentials from environment variables:

bash

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

3. Restart your MCP client

The client discovers tools on startup.

Service Filtering

Control which command groups the MCP server exposes:

bash

kraken mcp -s market                    # public data only (safe, no auth)
kraken mcp -s market,paper,feedback              # market data + paper trading (marketplace default)
kraken mcp -s market,trade,paper        # add live trading
kraken mcp -s market,account,trade      # add account queries and live trading
kraken mcp -s all                       # everything (many tools, includes funding/earn/subaccount)

Keep the service list to what you need. MCP clients typically handle 50-100 tools well.

Service	Auth	Tools	Risk
market	No	~10	None
account	Yes	~18	Read-only
trade	Yes	~9	Orders (dangerous)
funding	Yes	~10	Withdrawals (dangerous)
earn	Yes	~6	Staking (dangerous)
subaccount	Yes	~2	Transfers (dangerous)
futures	Mixed	~39	Orders (dangerous)
paper	No	~10	None (simulation)
auth	No	~3	Read-only (auth set/auth reset excluded)

Enabling live trading

Every kraken-cli marketplace listing ships with -s market,paper,feedback by default, so a fresh install can never place a real order. To opt in to live trading, edit the MCP server args in your client's config and widen the service list:

json

{
  "mcpServers": {
    "kraken": {
      "command": "kraken",
      "args": ["mcp", "-s", "market,trade,paper"],
      "env": {
        "KRAKEN_API_KEY": "your-key",
        "KRAKEN_API_SECRET": "your-secret"
      }
    }
  }
}

Recommended upgrade path:

Start with market,paper,feedback (the default).
Add trade once you are comfortable and have an API key scoped to orders only. See the "Recommended key scope" section of skills/kraken-setup/SKILL.md before generating a key.
Add account if you want the agent to read balances and positions.
Only enable funding, earn, subaccount, or all if you specifically need those workflows. Each of these unlocks tools that can move funds off the exchange or alter account structure.

Switching to -s all expands the set of tools the agent can reach by prompt-injection or mistake. Prefer a narrow list and widen it deliberately.

Safety

Dangerous tools include [DANGEROUS: requires human confirmation] in their description and carry the MCP destructive_hint annotation. In guarded mode (default), calls must include acknowledged=true. In autonomous mode (--allow-dangerous), the per-call confirmation is disabled. MCP clients that respect annotations may still prompt at the client layer.

For fully autonomous operation, see skills/kraken-autonomy-levels/SKILL.md.

Gemini CLI Extension

If using Gemini CLI, install the extension directly:

bash

gemini extensions install https://github.com/krakenfx/kraken-cli

The gemini-extension.json includes mcpServers config, so the MCP server starts automatically.

Troubleshooting

"No tools found": Check that kraken is on your PATH and the service list is valid. Run kraken mcp -s market manually to verify it starts.

Auth errors on tool calls: Set KRAKEN_API_KEY and KRAKEN_API_SECRET in the environment where your MCP client runs.

Too many tools: Reduce the service list. kraken mcp -s market,trade is a good starting point.

Streaming commands not available: WebSocket streaming commands are excluded from MCP v1. Use kraken ws ... directly from the terminal for streaming.

If you hit a mismatch between what you are trying to do and the CLI's interface or responses — including a mismatch between this skill and the installed CLI version's contract — feel free to submit feedback with kraken feedback.
