Run this in a terminal to add the server to Claude Code.
What this does
q-ring exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.
Requirements
This server needs the following environment variables to be set before it can run:
QRING_BACKEND QRING_FILE_PASSPHRASE QRING_FILE_BACKEND_PATH QRING_CONFIG_DIR
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
Frequently asked questions
