CortexHub Python SDK

Runtime governance for AI systems. One decorator. Any tool. Any framework.

pip install cortexhub

Python 3.10–3.12.

Quick start

Identity comes from your agent key only — the control plane assigns the canonical agent id. Set CORTEXHUB_AGENT_KEY (or pass agent_key= to init()).

import cortexhub

cx = cortexhub.init()  # requires CORTEXHUB_AGENT_KEY (or pass agent_key=)

@cx.tool
def process_payment(customer_id: str, amount: str, reference: str) -> dict:
    """Process a payment."""
    return payment_service.charge(customer_id, amount, reference)

# Policies, approvals, and audit trail are configured in the control plane.

Configuration

Env var	Description
CORTEXHUB_AGENT_KEY	Agent identity secret (required for cloud enforcement)
CORTEXHUB_DEBUG	Set to 1 or true for readable SDK logs: tool + arguments, policy name + condition, and decision
CORTEXHUB_LOG_LEVEL	e.g. DEBUG, INFO (default INFO)

Debug logging

With CORTEXHUB_DEBUG=1 (or CORTEXHUB_DEBUG_POLICY=1), the SDK logs in real time:

• Tool encountered — tool name and argument names/values (values redacted when privacy mode is on)
• Policy evaluated — policy name, condition/reasoning, and decision (allow / deny / escalate)
• Decision — final effect, policy, and reason for the current tool call

Useful for seeing exactly what CortexHub is evaluating and why a tool was allowed, blocked, or sent for approval.
