How do I install Signato?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Signato need an API key?

The publisher lists these environment variables: JOHARI_GUARD_CONFIG.

What transport does Signato use?

Signato runs locally over stdio.

Signato
