Cisco MCP Scanner — проверка безопасности MCP-серверов

★ 1K

mcp-scanner is Cisco's open-source tool for checking MCP servers for security threats. Reach for it when you connect tools to an AI assistant over the MCP protocol and need to be sure the server hides no dangers — commands that could do harm, injections in tool descriptions, data leaks. It scans three ways, together or singly: YARA rules, inspection through the Cisco AI Defense service, and analysis by the model itself. The practical point: MCP servers are often taken from open sources, and connecting an unvetted one means giving it access to your systems blind; the scanner removes that blindness. Written in Python, it fits into a review pipeline before a server is connected. It helps teams rolling out agents who are responsible for their security.
