# Unbrowse

Unbrowse routes website tasks through first-party APIs instead of headless browsers. It speeds up web interactions and lowers costs for autonomous agents.

## What it does

The tool replaces browser automation by directly calling the HTTP endpoints that web frontends use. When a domain is already registered in private capabilities or the public tool registry, the agent completes tasks without opening a headless browser instance.

For unmapped targets, Unbrowse learns endpoints from two recorded HAR archives with `unbrowse learn`, or runs an initial pass inside a cloud-hosted browser. User passwords remain inside the hosted password manager. They never pass through the CLI interface.

Execution requires connectivity to `https://unbrowse.ai/mcp`. You must authenticate via `npx unbrowse login` or set the `UNBROWSE_API_KEY` token.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://unbrowse.ai/mcp`
- Environment variables: `UNBROWSE_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
