PURU Suisse launches MoltenRock on the Mac App Store

PURU Suisse GmbH has published MoltenRock, a Swiss-built Mac app that puts users in control of the credentials AI agents can access. The free app launched worldwide Aug. 19, 2026 with an optional Pro tier and local-only security features built around Apple’s Secure Enclave.

Why it matters: - MoltenRock targets a growing risk in AI workflows: agents handling email, API keys and other sensitive credentials stored in plaintext on users’ machines. - The app is designed to give users scoped, logged and revocable control over what AI agents can access. - PURU Suisse positions the product for professional use with a privacy-first, local-only architecture.

What happened: - PURU Suisse GmbH announced the publication of MoltenRock on the Mac App Store on Aug. 19, 2026. - The app is available worldwide as a free download with an optional Pro tier. - MoltenRock is a Swiss-built Mac application that gives users secure control over the credentials their AI agents use. - The app also has a notarized direct download at MoltenRock.

The details: - MoltenRock stores API keys and email credentials in an encrypted vault protected by the Mac’s Secure Enclave on Apple Silicon or T2 Macs. - Users can assign per-agent permissions and decide which agent may use which key or mailbox. - Every credential access is recorded in a full activity log. - Users can revoke access and lock the vault with a seal. - The local email bridge lets AI agents read email and prepare drafts only. - Drafts are saved to the mailbox’s own Drafts folder for user review and sending. - The agent cannot send or delete email. - The mailbox password never leaves the application. - The architecture is fully local, with no cloud, no account and no telemetry. - MoltenRock works with local AI agents and includes a dedicated secrets integration for OpenClaw. - The integration is meant to move API keys out of plaintext configuration files and into the vault. - MoltenRock is part of a local-first family that also includes MoltenMail and MoltenView. - More information about the application family is available at Swift Applications.

Between the lines: - The launch reflects a push to add a trust layer around AI agents as they gain access to business-critical tools. - By keeping credentials local and encrypted, PURU Suisse is betting on privacy and auditability as selling points. - The company is also tying MoltenRock into a broader product ecosystem, which can make the app more useful for users already working with its other local-first tools.

What’s next: - PURU Suisse says MoltenRock is built for professional use and will likely compete on control, compliance and local security. - The product’s adoption may depend on whether users want to move AI-agent credentials out of configuration files and into a managed vault. - Business and licensing inquiries go to Goldcote.

The bottom line: - MoltenRock gives Mac users a local, auditable way to let AI agents use sensitive credentials without handing over full access.
