"author:rephuren" matching MCP servers:

A security gateway that sits between an MCP client and real MCP servers, routing every tool call through namespace isolation, definition pinning, argument and rate policies, taint tracking, and response injection checks. It blocks tool shadowing, rug pulls, hidden Unicode payloads, path traversal, and exfiltration of private data to outside channels, while logging each decision and requiring out-of-band human approval for sensitive calls.
