What MoltenRock does
MoltenRock
An encrypted vault for your API keys and email credentials, protected by your Mac’s Secure Enclave. It serves them to the local AI agents you allow, key by key, and logs every use, so secrets stop living in plain-text config files.
MoltenMail
Secure email for you and your AI, read and draft only. Your agent reads, searches and drafts; every reply lands in your own Drafts folder for you to review and send. It can never send, delete or move a message.
MoltenRock Connect
Your business tools for your AI agent: Shopify, WooCommerce, Stripe and 28 more platforms. Every request is audited and customer names are tokenised by default, so an agent can answer questions about your business; it can change something only by proposing it in the Human Queue, and only once you approve.
MoltenView
A secure canvas where your AI agents render visual content and interactive displays, locally, without your data leaving your Mac.
The Human Queue
Live in MoltenRock Connect, starting with Stripe: every change an agent proposes, such as a refund or an invoice, waits until you approve it with Touch ID. Connect then sends it; the agent never holds a write key. Cloudflare is next.
What makes MoltenRock different
Your Mac’s Secure Enclave, not someone else’s cloud
Keys are encrypted with hardware-backed keys on your own Mac. Doppler, Infisical and HashiCorp Vault run secrets as a cloud or server service, and 1Password syncs them through its cloud; MoltenRock keeps them on the machine where your agents actually run.
Built for AI agents, not people typing passwords
Each agent gets its own per-key grants, every access lands in an activity log, and one click revokes it. The agent gets access to a key without the raw secret sitting in its context or a .env file.
No account, no cloud, no telemetry
You don’t sign up to use it, your secrets never sync to any server, and the apps collect no usage data. A recovery phrase backs up the vault, and a seal switch locks everything instantly.
Nothing changes without you
MoltenMail can draft but never send. MoltenRock Connect lets an agent read across 31 platforms, and change something only by proposing it in the Human Queue (Stripe today) for you to approve. Automation tools such as Zapier are built to act on your behalf; MoltenRock’s apps let an agent look, and ask, without being able to act on its own.
Free to start
MoltenRock, MoltenMail, MoltenRock Connect and MoltenView are all free to download. MoltenRock Pro, from $9.99 a month, adds unlimited keys and mailboxes and the MoltenRock Connect vault.
Who MoltenRock is for
- Developers running local agents such as OpenClaw, Hermes, Claude Code, Cursor and Codex who want their API keys out of .env files.
- Mac power users and AI-first professionals who want an assistant to triage and draft email without handing over their password.
- Shopify, WooCommerce and Stripe merchants who want an agent to answer questions about orders, payments and shipping without write access.
- Privacy-conscious people and teams who want every agent access logged and revocable, on hardware they control.
