Legal notices¶
About & disclaimer¶
Tulip is maintained independently by The Tulip Authors. The maintainers develop the project in the open and do not claim endorsement by model providers or integration vendors. Its licensing history is described under Provenance.
Released under the Apache License, Version 2.0.
Disclaimer of warranty and liability¶
The software is provided "AS IS", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and non-infringement. The maintainers accept no liability for any claim, damages, or other consequence arising from the software or its use. Use is entirely at your own risk. You are solely responsible for ensuring that your use is lawful, authorized, and compliant with all applicable obligations — including security, privacy, export-control, and any policies that govern the systems and data you touch.
Responsible use¶
The core tulip-agents package does not include offensive-capable tooling. The separate, opt-in tulip-agents-security package does — red-team agents, model and hardware fingerprinting, and similar reconnaissance capabilities. Use it only against systems you own or are explicitly authorized to test. Running these capabilities against systems you do not own or have not been authorized to assess may be unlawful.
