Sulcus Launches AI Agent Runtime Observability and Control Tool

KEY FACTS

  • Sulcus can observe and control AI agents while they are running.
  • Hosted runs integrate automatically with frameworks such as LangGraph and CrewAI, with no code changes required.
  • Local Claude Code and Codex require installing the Sulcus command-line tool.
  • Hosted runs can stop agents, while local runs only allow approving actions and cannot terminate them.
  • The framework integrations do not collect prompts, model responses, or tool inputs and outputs.

KEY DATA

3Number of environment variables
4Number of supported frameworks

PHYSIX OBSERVATION

Sulcus hits the pain point of AI agent security governance, but its capabilities are constrained by deployment method, and local control is weak. Its not collecting sensitive data is a highlight, but users must pay for model costs themselves, which may affect adoption. The industry needs more unified observability standards.
