What can you do with this server?

The qring-mcp server provides a quantum-inspired secret/credential management system for AI coding agents, securely anchoring credentials to your OS's native vault (macOS Keychain, GNOME Keyring, Windows Credential Manager) with 20 specialized tools. Core Secret Management * get_secret / set_secret / delete_secret / has_secret / list_secrets — full CRUD with scope control (global/project); values never exposed in listings * inspect_secret — view full metadata (TTL, environment states, entanglement, access history) without revealing values Quantum-Inspired Features * Superposition: Store environment-specific values (dev/staging/prod) that auto-resolve based on context * Wavefunction Collapse (detect_environment): Auto-detect environment via flags, env vars, git branches, or project config * Quantum Decay: Set TTL so secrets expire automatically; expired secrets return false on existence checks * Entanglement (entangle_secrets): Link secrets so updates to one automatically propagate to the other * Quantum Noise (generate_secret): Generate cryptographically strong secrets (hex, UUID, API key, password, token) with optional auto-save Advanced Security * Tunneling (tunnel_create/read/list/destroy): Ephemeral in-memory secrets that never touch disk, with optional self-destruction after a time limit or number of reads * Teleportation (teleport_pack/unpack): Encrypt secrets into AES-256-GCM bundles for secure transfer between machines, with dry-run preview on import Monitoring & Audit * Observer Effect (audit_log): Full audit trail of all reads, writes, and deletes * detect_anomalies: Identify unusual patterns (burst access, off-hours access) with recommendations * health_check: Comprehensive report on decay status, staleness, anomalies, and entropy * agent_scan: Autonomous monitoring scan across secrets and projects, with optional auto-rotation of expired secrets Works seamlessly with Cursor, Kiro, Claude Code, and the broader MCP ecosystem.

Which integrations are available for this server?

Provides a secure, encrypted alternative to storing sensitive API keys in plain-text .env files. Uses Git branch heuristics to automatically detect environments and resolve the correct secret values. Anchors credentials to the native GNOME Keyring to provide OS-level security for secrets on Linux. Anchors credentials to the native macOS Keychain to provide secure, OS-level secret management. Manages OpenAI API keys with advanced features like environment-specific resolution and access auditing. Facilitates the generation and secure storage of Stripe API keys within the native OS vault.

q-ring

The first quantum-inspired keyring built specifically for AI coding agents.

Stop pasting API keys into plain-text .env files or struggling with clunky secret managers. q-ring securely anchors your credentials to your OS's native vault (macOS Keychain, GNOME Keyring, Windows Credential Manager), then supercharges them with mechanics from quantum physics.

Experience superposition (multi-environment keys), entanglement (linked rotations), tunneling (in-memory ephemerality), and teleportation (encrypted sharing).

Seamlessly integrated with Cursor, Kiro, Claude Code, and the entire MCP ecosystem.

🚀 Installation

q-ring is designed to be installed globally so it's available anywhere in your terminal. Pick your favorite package manager:

# npm
npm install -g @i4ctime/q-ring

# pnpm (recommended)
pnpm add -g @i4ctime/q-ring

# yarn
yarn global add @i4ctime/q-ring

⚡ Quick Start

# 1️⃣ Store a secret (prompts securely if value is omitted)
qring set OPENAI_API_KEY sk-...

# 2️⃣ Retrieve it anytime
qring get OPENAI_API_KEY

# 3️⃣ List all keys (values are never shown)
qring list

# 4️⃣ Generate a cryptographic secret and save it
qring generate --format api-key --prefix "sk-" --save MY_KEY

# 5️⃣ Run a full health scan
qring health

Quantum Features

Superposition — One Key, Multiple Environments

A single secret can hold different values for dev, staging, and prod simultaneously. The correct value resolves based on your current context.

# Set environment-specific values
qring set API_KEY "sk-dev-123" --env dev
qring set API_KEY "sk-stg-456" --env staging
qring set API_KEY "sk-prod-789" --env prod

# Value resolves based on context
QRING_ENV=prod qring get API_KEY   # → sk-prod-789
QRING_ENV=dev  qring get API_KEY   # → sk-dev-123

# Inspect the quantum state
qring inspect API_KEY

Wavefunction Collapse — Smart Environment Detection

q-ring auto-detects your environment without explicit flags. Resolution order:

--env flag
QRING_ENV environment variable
NODE_ENV environment variable
Git branch heuristics (main/master → prod, develop → dev)
.q-ring.json project config
Default environment from the secret

# See what environment q-ring detects
qring env

# Project config (.q-ring.json)
echo '{"env": "staging", "branchMap": {"release/*": "staging"}}' > .q-ring.json

Quantum Decay — Secrets with TTL

Secrets can have a time-to-live. Expired secrets are blocked from reads. Stale secrets (75%+ lifetime) trigger warnings.

# Set a secret that expires in 1 hour
qring set SESSION_TOKEN "tok-..." --ttl 3600

# Set with explicit expiry
qring set CERT_KEY "..." --expires "2026-06-01T00:00:00Z"

# Health check shows decay status
qring health

Observer Effect — Audit Everything

Every secret read, write, and delete is logged. Access patterns are tracked for anomaly detection.

# View audit log
qring audit
qring audit --key OPENAI_KEY --limit 50

# Detect anomalies (burst access, unusual hours)
qring audit --anomalies

Quantum Noise — Secret Generation

Generate cryptographically strong secrets in common formats.

qring generate                          # API key (default)
qring generate --format password -l 32  # Strong password
qring generate --format uuid            # UUID v4
qring generate --format token           # Base64url token
qring generate --format hex -l 64       # 64-byte hex
qring generate --format api-key --prefix "sk-live-" --save STRIPE_KEY

Entanglement — Linked Secrets

Link secrets across projects. When you rotate one, all entangled copies update automatically.

# Entangle two secrets
qring entangle API_KEY API_KEY_BACKUP

# Now updating API_KEY also updates API_KEY_BACKUP
qring set API_KEY "new-value"

Tunneling — Ephemeral Secrets

Create secrets that exist only in memory. They never touch disk. Optional TTL and max-read self-destruction.

# Create an ephemeral secret (returns tunnel ID)
qring tunnel create "temporary-token-xyz" --ttl 300 --max-reads 1

# Read it (self-destructs after this read)
qring tunnel read tun_abc123

# List active tunnels
qring tunnel list

Pack secrets into AES-256-GCM encrypted bundles for secure transfer between machines.

# Pack secrets (prompts for passphrase)
qring teleport pack --keys "API_KEY,DB_PASS" > bundle.txt

# On another machine: unpack (prompts for passphrase)
cat bundle.txt | qring teleport unpack

# Preview without importing
qring teleport unpack <bundle> --dry-run

Agent Mode — Autonomous Monitoring

A background daemon that continuously monitors secret health, detects anomalies, and optionally auto-rotates expired secrets.

# Start the agent
qring agent --interval 60 --verbose

# With auto-rotation of expired secrets
qring agent --auto-rotate

# Single scan (for CI/cron)
qring agent --once
