What is this MCP
Hronaut is a visible Electron/Chromium desktop browser with an embedded local Streamable HTTP MCP server. It provides persistent, isolated browser workspaces that remain available across coding agent conversations, with visible human oversight and takeover capabilities.
How to use this MCP
Install and start the Hronaut desktop application before connecting your AI agent. Copy the current endpoint and authentication configuration from the Hronaut Home interface. The browser maintains tabs, cookies, and isolated workspace profiles independently of agent sessions. Use the pause feature to block new MCP requests (note: it doesn't cancel commands already in flight).
What this MCP can be used for
This MCP enables AI coding agents to interact with web applications through persistent browser sessions. It's useful for web automation, testing, data extraction, and maintaining logged-in states across sessions. The visible interface allows human monitoring and intervention, making it suitable for collaborative workflows where agents need consistent browser environments.
