browser_get_cookies
Export cookies for curl / scripts
How to use it
Project documentation lists browser_get_cookies for the Byob 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.
