How It Fits Together
LangChain • Google ADK • CrewAI • AutoGen • OpenAI Agents • RAG
LangChain / LangGraph
Add a callback handler to any LangChain agent or chain. Works with LangGraph too. Automatic audit trails, PII detection, consent gates, and injection scanning.
Google ADK
Plugin for Google's Agent Development Kit. Drop into any ADK agent with one line. Automatic tool risk classification, audit chains, and policy enforcement.
Gate Server
Centralized policy enforcement for multi-agent architectures. Docker Compose stack with real-time dashboard and Jaeger tracing. One command to start.
End-to-End Demo
See the full flow: start Gate, connect an agent, watch policy decisions happen in real time, and verify the tamper-evident audit chain.
Gate starts with Docker Compose
Brings up the Gate API (port 8000), real-time Dashboard (port 3000), and Jaeger distributed tracing (port 16686) in one command.
Agents submit tool calls to Gate
Each trust layer checks with Gate before executing a tool. Gate evaluates the action against your policy rules and returns allow, block, or require_approval.
Every decision is logged in a tamper-evident chain
HMAC-SHA256 hashes link each audit entry to the previous one. If anyone modifies or deletes an entry, the chain breaks and verification fails.
Humans approve pending actions via Dashboard
High-risk actions wait for human approval. The Dashboard shows pending actions in real time. Approve or reject with one click.
Export the audit chain for regulators
The full audit trail is exportable as JSON — timestamped, signed, and verifiable. Ready for EU AI Act Article 12 compliance submissions.
