HELM governance adapter for crewai — fail-closed tool calling for AI agents

helm-crewai

HELM governance adapter for CrewAI.

What it does

Wraps CrewAI agent tools with HELM governance:

1. Every tool call is evaluated against HELM policy before execution
2. Denied calls raise HelmToolDenyError (fail-closed by default)
3. Per-agent principal tracking for multi-agent crew governance
4. Receipts with SHA-256 hashes are collected for every approved execution

Quick start

from helm_crewai import HelmCrewGovernor

governor = HelmCrewGovernor(helm_url="http://localhost:8080")
governed_tools = governor.govern_tools(my_tools, agent_role="researcher")

# Use in a CrewAI agent
agent = Agent(role="researcher", tools=governed_tools)

Configuration

Parameter	Default	Description
helm_url	http://localhost:8080	HELM kernel URL
api_key	None	HELM API key
fail_closed	True	Deny on HELM errors
collect_receipts	True	Keep receipt chain
