get_frame_tree

MCP tool from Crawlio Browser by Crawlio-app

Get frame hierarchy (main + iframes)

How to use it

Project documentation lists get_frame_tree for the Crawlio Browser MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
