mcpsnoop

Wireshark-style transparent proxy that shows every real MCP tool call between your AI client and servers live.

Desktopfreeglobal

This is a proxy tool that shows every real tool call passing between an AI client, such as Cursor or Claude Code, and the external tool servers it connects to, displayed live in a terminal interface. Because it sits in the actual data path rather than connecting as a separate client, it can flag hung calls, malformed messages, and tool definitions that changed after approval. It suits developers debugging or auditing that kind of traffic, including as an automated CI check.
