In-memory privacy shield to prevent context leaks in MCP tools

Rohan Protocol has released an open-source Model Context Protocol (MCP) server that acts as a security gateway to prevent sensitive data leaks during tool execution. The in-memory privacy shield isolates tool arguments in RAM and immediately wipes them using deterministic memory zeroization, ensuring credentials and context never enter the LLM's plaintext conversation window. The project is currently in public beta (v0.6.0) and uses client-side RAM witness isolation and semantic policy firewalls, with native WASM zero-knowledge proving circuits under active development.
