QNSQY

Overview

QNSQY is a Model Context Protocol server that performs post-quantum CBOM scans, encrypts to public keys, and verifies signatures—all without handling secrets. Running on Linux, it integrates directly with your AI assistant to expose these security capabilities as tools the model can call on your behalf.

The server operates entirely locally via the npm package qnsqy, communicating over stdio with no authentication required. Install it with npx -y qnsqy and start using it immediately. Version v7.2.49 is the latest release.

QNSQY belongs in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain QNSQY for quantumsequrity, claim this listing to verify ownership and keep the information up to date.
