Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
QRING_BACKENDOptional | Secret storage backend. Defaults to the OS keychain; set to "file" for headless hosts with no Secret Service (CI, containers). |
QRING_FILE_PASSPHRASEOptional, secret | Passphrase for the encrypted file backend (AES-256-GCM). Required only when QRING_BACKEND=file — without it the file backend fails closed. |
QRING_FILE_BACKEND_PATHOptional | Custom path for the encrypted file store (default: ~/.config/q-ring/file-backend.enc). |
QRING_CONFIG_DIROptional | Directory for q-ring's registries — hooks, entanglement, approvals, canary webhooks, agent memory (default: ~/.config/q-ring). |
