Show HN: Reverse-engineering web apps into agent tools

According to Hacker News, a team has developed a browser-based agent that learns what a web app can do by simply watching it work. The agent runs inside an authenticated application and observes the API calls the app makes to itself. From those observations, it automatically extracts the tools an AI assistant would need: API endpoints, authentication methods, request schemas, and response patterns—all reverse-engineered without touching the app's source code. If an API changes, the agent updates its tools automatically. This tackles a real problem in AI integration: most modern apps have fragmented, poorly-documented APIs that AI agents can't reliably use out of the box. Manual MCP servers or custom code become unnecessary. The team demonstrated the approach working with Jira, Spotify, and Hacker News itself, showing AI completing complex tasks like team workspace invitations by learning how the app already functions.
