Lets your AI store, fetch, and manage your app passwords and API keys safely in your computer's own keychain.

Security Privacy For it and development Security

q-ring is a small helper that keeps your secret passwords and API keys in the secure vault that already comes with your computer, like the Mac Keychain or Windows Credential Vault. It also plugs into AI coding tools such as Cursor, Kiro, and Claude Code, so your AI can look up a key or save a new one when you ask. It is handy if you keep pasting keys into plain text files and want a safer, tidier way.

What is an MCP server? The 30-second version

On its own, your AI can only chat. It cannot reach into your computer or your apps. An MCP server is a small helper program that gives your AI one new skill. Here, q-ring is that helper: it connects your AI to your computer's built-in password vault, so the AI can store, find, and manage your secret keys for you.

What this MCP server does

You ask your AI something like "save this key" or "what is my OpenAI key?". The AI passes that request to q-ring. q-ring then talks to your computer's own secure vault, where the real value lives. It sends back just the answer you need, like the key value or a confirmation that it was saved. Your secrets never sit in a plain text file unless you explicitly export them.

Flow diagram: you ask your AI “Save my new Stripe key as STRIPE_KEY”, on your own computer the q-ring MCP server works with your computer's keychain, and you get back the key value or a saved confirmation.

“What is the value of my OPENAI_API_KEY?”
“List all the secrets I have saved”
“Generate a strong password and save it as DB_PASSWORD”

What it gives back to you

You get back plain answers in the chat. If you ask for a key, the AI shows you the value. If you save one, it confirms it was stored. If you list your secrets, you see the names only, never the values. It can also show you a health report or a list of expired keys.
