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

helm-autogen

HELM governance adapter for Microsoft AutoGen.

What it does

Governs AutoGen multi-agent function and tool calls through HELM:

1. Every function_call and tool invocation is evaluated against HELM policy before execution
2. Denied calls raise HelmToolDenyError (fail-closed by default)
3. Receipts with SHA-256 hashes are collected for every approved execution

Quick start

from helm_autogen import HelmAutoGenGovernor

governor = HelmAutoGenGovernor(helm_url="http://localhost:8080")
governed_fn = governor.govern_tool("code_exec", execute_code, agent_name="assistant")
# Or govern messages with function_call fields
governor.govern_message(message, agent_name="assistant")

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
