Kakunin Samples — AI agent identity & compliance examples (X.509, scope enforcement, LangChain/CrewAI/Next.js)

Comply with MiCA Art. 72 and EU AI Act in under 10 minutes.

End-to-end integration samples for the Kakunin AI agent compliance API.

⭐ If this saves you compliance headaches, star this repo.

Kakunin issues X.509 cryptographic identities to AI agents, monitors their behaviour in real time, and generates MiCA & EU AI Act compliance reports — all via API.

Quickstart

Prerequisites: API key from dashboard → API Keys

TypeScript (Node ≥ 18):

cd typescript && npm install
KAKUNIN_API_KEY=kak_live_... npx ts-node quickstart.ts

Python (3.10+):

cd python && pip install -r requirements.txt
KAKUNIN_API_KEY=kak_live_... python quickstart.py

curl:

KAKUNIN_API_KEY=kak_live_... ./curl/quickstart.sh

Go:

KAKUNIN_API_KEY=kak_live_... go run go/main.go

---

Framework integrations

The kakunin Python SDK ships scope-enforcement wrappers for all major agentic frameworks:

pip install kakunin

Integration	Class	Scope check fires
LangChain	KakuninToolGuard	Per-tool invocation
LangChain	langchain_scope_callback	Per-chain (before first LLM call)
LlamaIndex	KakuninFunctionToolGuard	Per-tool call
CrewAI	KakuninCrewAgent	Per-task execution
AutoGen	KakuninConversableAgent	Per-reply

See langchain/ for a full example. Full reference: kakunin.ai/docs/python-sdk.

Use in CI (reusable GitHub Actions workflow)

jobs:
  certify:
    uses: kakunin-ai/kakunin-samples/.github/workflows/certify-agent.yml@main
    with:
      agent_name: my-production-agent
      model: gpt-4o
      version: ${{ github.sha }}
    secrets:
      KAK_API_KEY: ${{ secrets.KAKUNIN_API_KEY }}

Outputs agent_id and cert_serial for downstream steps. See .github/workflows/certify-agent.yml.
