Firefighter

Firefighter is an automated server patching tool that uses an LLM with root access to continuously fix vulnerabilities.

Firefighter is a server patching tool that constantly and continuously maintains your server. It operates as a root service with zero confirmations, using an LLM to investigate versions, exposures, logs, and evidence. The system listens to official vulnerability sources centrally, investigates locally, applies package or code fixes, tests changes, contains exposures, and invokes key rotation hooks. It then verifies the fix and service health, uses rollback when supplied, and sends a report to an agent of your choice. Commands, results, verification, and recovery attempts are recorded in a local audit trail.
