Description
NetBox MCP Server is a simple read-only Model Context Protocol server for NetBox. Prior to version 1.2.1, when running with TRANSPORT=http, the MCP server has no authentication on the HTTP endpoint. Any client that can reach the port gets a valid MCP session and full access to all four NetBox tools - no token or credential needed. This issue has been patched in version 1.2.1.
