[pi-browser-use](https://github.com/TGYD-helige/pi) is a pi-coding-agent extension that wraps [chrome-devtools-mcp](https://github.com/ChromeDevTools/chrome-devtools-mcp), exposing all browser automation tools with a unified `browser_` prefix.

## Features
|
|
|
|
- **Dynamic tool discovery** — auto-proxies all upstream chrome-devtools-mcp tools with `browser_` prefix
|
|
- **Tool description augmentation** — adds usage hints for key tools
|
|
- **Result post-processing** — strips embedded snapshots, detects overlay/stale element issues
|
|
- **Optional visual analysis** — `browser_analyze_screenshot` via configurable vision model
|
|
- **Standalone mode** — runnable as independent MCP server via CLI
|
|
|
|
