Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

Run this in your terminal

claude mcp add kakunin --env KAKUNIN_API_KEY=your-value --env KAKUNIN_AGENT_ID=your-value -- npx -y @kakunin/mcp

Fill in the empty values before running it.

Common questions

Is Kakunin safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: KAKUNIN_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.3) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@kakunin/mcp — MCP server for AI agent identity & compliance

Model Context Protocol server for the Kakunin AI agent compliance API. Lets AI agents self-verify scope, check their own risk score, and log behavioral events — all from within Claude, Cursor, or any MCP-compatible runtime.

npx @kakunin/mcp

Tools

`verify_agent_scope`

Check whether this agent is authorised to perform an action before executing it. Verifies the active X.509 certificate, permitted_actions scope, financial limits, and revocation status.

"action": "initiate EUR/USD trade on euronext for 50000 USD", "venue": "euronext", "amount_usd": 50000 }

Returns { allowed: true|false, reason, certificate_status, permitted_actions }.

`check_risk_score`

Retrieve the agent's rolling 30-day risk score, band (low/medium/high), drift trend, and actionable guidance. No input required.

`audit_log_append`

Append a behavioral event to the agent's immutable audit log. Returns risk score + transaction ID. Events scoring ≥ 0.85 auto-trigger a certificate revocation check.

"action_type": "transaction_initiated", "details": { "amount_usd": 50000, "venue": "NYSE" } }

Setup

Prerequisites: Node ≥ 18, Kakunin API key + Agent ID from kakunin.ai/dashboard.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

"mcpServers": { "kakunin": { "command": "npx", "args": ["-y", "@kakunin/mcp"], "env": { "KAKUNIN_API_KEY": "kak_live_...", "KAKUNIN_AGENT_ID": "agt_..." } } } }

Environment variables

Variable	Required	Description
`KAKUNIN_API_KEY`	✅	API key (`kak_live_...` or `kak_test_...`)
`KAKUNIN_AGENT_ID`	✅	Agent ID the server acts on behalf of
`KAKUNIN_BASE_URL`	optional	Override API base (default: `https://kakunin.ai`)

Sandbox mode

Use a kak_test_... key for development — hits the sandbox CA, no cost, 100 free certs/day.
