tcp_probe

MCP tool from Fingerprint MCP by badchars

TCP connect scan to detect open ports

How to use it

Project documentation lists tcp_probe for the Fingerprint MCP 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.
