Could you build this?
Yes It is a terminal UI proxy that intercepts JSON-RPC standard I/O or SSE traffic between an MCP host and client, a classic pattern well-suited for AI-assisted coding.
Discussion
20 comments analyzed.
Competitors mentioned: tshark (shell alternative), LiteLLM (pre-execution firewall with audit trail), Aegis (pre-execution firewall with audit trail), MCP Inspector (similar traffic monitoring)
Concerns raised: Authorization headers and bearer tokens may be captured in payloads, Payload secrets end up in traces if contained in JSON-RPC messages, Many AI auditability proxies already exist in the market
Feature requests: Simple redact config (keys/patterns to scrub before writing traces), Web/browser interface to visualize and browse trace data, Remote debugging and post-mortem debugging support, Automatic MCP discovery, installation, and security management
