What is the Q MCP Server?

Quantum-inspired keyring for AI coding agents with superposition, entanglement, and tunneling.

The short version

Stop pasting API keys into plain-text .env files or wrestling with clunky secret managers. q-ring securely anchors your credentials to your OS's native vault (macOS Keychain, Linux Secret Service, Windows Credential Vault) and supercharges them with mechanics from quantum physics.

  • Superposition: — Store one key with multiple states (dev/staging/prod) that collapse based on context
  • Entanglement: — Link keys across projects so rotating one automatically updates them all
  • Tunneling: — Create ephemeral, in-memory secrets that self-destruct after a set time or read count
  • Teleportation: — Securely pack and share AES-256-GCM encrypted secret bundles
  • Seamless AI Integration: — 44 built-in MCP tools for native use in Cursor, Kiro, and Claude Code

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

ToolWhat it does
get_secretRead a secret value (collapses superposition, audits the read)
list_secretsList keys + metadata in scope (values never exposed); filter by tag, expiry, glob
set_secretCreate or overwrite a single secret with optional TTL, per-env state, tags, rotation format
delete_secretPermanently remove a secret value (not undoable from q-ring)
has_secretBoolean existence check that respects decay (no audit read)
export_secretsRender multiple secrets as .env or JSON for one-off export (skips approval-protected keys without a grant)
import_dotenvParse .env text and bulk-store every key/value pair (accepts raw content only — never reads files)
check_projectCompare .q-ring.json manifest against the keyring for missing/expired/stale keys
env_generateRender a complete .env body from the project manifest, with warnings for gaps
