In-memory privacy shield to prevent context leaks in MCP tools
The Rohan protocol introduces an in-memory security proxy designed to prevent context leaks and credential exfiltration in Model Context Protocol (MCP) tools. It uses memory isolation and zeroization to ensure sensitive data does not enter the LLM context window.
Why it matters
As autonomous agents become more integrated with tools, securing the data flow between them is critical to preventing security breaches and data exposure.
Official Model Context Protocol (MCP) Server & Security Gateway The in-memory security proxy preventing LLM context leaks, credential exfiltration, and prompt injections during tool execution.
📦 Official Open-Source MCP Server Monorepo The core Model Context Protocol (MCP) server implementation is located directly in this repository at packages/mcp/ and distributed on npm as @rohan-protocol/mcp .

⚠️ Public Beta (v0.6.0): Rohan currently enforces client-side RAM witness isolation, V-01 semantic policy firewalls, and V-02 deterministic memory zeroization (zeroize) to shield MCP tool calls while native client-side WASM ZK-SNARK proving circuits are under active research (Milestone 1).
The Model Context Protocol (MCP) connects autonomous agents to tools. However, transport encryption (TLS) only protects data in flight — at the host boundary, standard MCP tools execute in cleartext:
