Tamper-evident, compliance-grade logs of every agent action in CrewAI agents — without rewriting your code, without adding a proxy to the request path.
The problem
CrewAI is great at what it does, but production-grade audit logging is bring-your-own. Most teams discover this when the first production incident hits, the first OpenAI bill arrives, or the first auditor asks for evidence.
Specifically:
- Crew-level cost easily runs 5-10× single-agent cost — opaque without tooling
- Role-based access control isn't enforced — any agent can call any tool
- Long task chains can drift without continuous evaluation
How Prefactor solves it
Prefactor wraps your CrewAI Crew and adds audit logging as a runtime layer. Specifically:
- SOC 2 evidence collection
- EU AI Act Article 12 record-keeping
- ISO 42001 documentation lifecycle
- auditor-ready exports
- incident forensics
Install and integrate
pip install prefactor-crewaifrom crewai import Crew
from prefactor import Prefactor
pf = Prefactor(api_key="pf_live_...")
crew = pf.wrap(Crew(agents=[...], tasks=[...]), crew_id="research-crew")Specific use cases
- Soc 2 evidence collection
- Eu ai act article 12 record-keeping
- Iso 42001 documentation lifecycle
- Auditor-ready exports
- Incident forensics
FAQ
Does this add latency? Per-span instrumentation adds ~2-5ms. Telemetry ships asynchronously. No synchronous network call in the agent's hot path unless you enable blocking policy enforcement.
Can I configure this per-agent? Yes. Audit Logging settings are per-agent — different agents can have different policies, sampling rates, retention, etc.
Is this compatible with other observability tools? Yes. Prefactor exports OpenTelemetry; works alongside Datadog, Langfuse, LangSmith, and others.
