export_json

MCP tool from MCP Wireshark by khuynh22

Export packets from a pcap to a JSON file at a path you choose

How to use it

Project documentation lists export_json for the MCP Wireshark 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.
