Project overview
The short version
Causeway is a standalone Rust bridge between MCP clients and Chromium. It receives tool calls over standard input and sends the corresponding commands through the Chrome DevTools Protocol. The public landing page groups its browser tools around navigation, tabs, clicks, forms, screenshots, page reading, waits, network inspection, console inspection, and chained actions.
