My public work is primarily upstream engineering. I reproduce the condition, locate the violated invariant, make the narrowest defensible change, and leave behind evidence that explains why it is correct.

A security-first observability proxy for Model Context Protocol traffic over local stdio and Streamable HTTP. It can sit between an MCP client and a subprocess without a shell, preserve protocol bytes, keep server diagnostics off stdout, and record redacted request/response metadata for later inspection. The project also includes safe HTTP replay, offline HTML reports, Prometheus metrics, OpenTelemetry export, a deterministic demo, and explicit compatibility and security boundaries.
