CrewAI

Drop-in tool wrapper for CrewAI agents.

from crewai_tools import BaseTool
from interven_crewai import guard

raw_tool = MySalesforceTool()
guarded = guard(raw_tool, api_key="iv_live_...")

crew = Crew(
    agents=[my_agent],
    tasks=[task],
    tools=[guarded],
)

guard() wraps the tool's _run method. Every CrewAI invocation goes through Interven before reaching the upstream.

Install

pip install interven-crewai

Depends on interven + crewai>=0.36.

Behavior

  • ALLOW → tool runs normally with the original arguments
  • DENY → raises InterventBlockedError
  • SANITIZE → tool runs with redacted arguments
  • REQUIRE_APPROVAL → blocks until analyst approves; returns the upstream result on resume

LangChain

Wrap your LangChain tools or attach an Interven callback handler.

OpenAI Assistants

Scan tool_calls before the assistant executes them.
