Agent Browser MCP

A self-hosted MCP server that provides AI agents with control over a single headed Chrome session via a bounded JSON API. It allows agents to navigate, inspect, click, type, and scroll, while offering a live noVNC view for human oversight and takeover when the agent encounters obstacles like 2FA prompts.
