legacy-use
Open-source tool exposing legacy desktop apps via REST API so AI agents can control them via GUI automation.
🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for legacy-use, derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification.

Overview
legacy-use is an open-source platform that wraps legacy or desktop software and exposes functionality via REST APIs. It simulates GUI interactions (e.g. via VNC, RDP) to allow AI or agentic systems to invoke operations on software that lacks built-in interfaces. It supports prompt-based endpoint generation, model-provider independence, built-in logging, debugging, and optional guardrails and enterprise deployments.
