What it does
An MCP server by CatchNip for creating and managing Selenium Grid browser instances, aimed at agents and automation workflows that need browsers on demand. It can run Chrome, Firefox and Edge nodes either in Docker or on Kubernetes (K3s is mentioned), and is run with uv. The server listens on a local port and offers both streamable HTTP and SSE endpoints, with a stdio option for MCP clients; browser management can be protected with token authentication, and the Grid itself takes a username, password and VNC password set in the environment. The README notes that stdio mode needs a manual clean-up command afterwards.
Capabilities
- Create and remove Selenium Grid browser instances
- Run Chrome, Firefox and Edge nodes
- Deploy browsers on Docker or Kubernetes
