A local Mac vault vs a cloud secrets manager, for AI agents
HashiCorp Vault, Doppler, Infisical and cloud providers’ secret stores run your production secrets well. The agent on your laptop is a different problem.
The short answer
Cloud secrets managers such as HashiCorp Vault, Doppler and Infisical are services for servers, pipelines and teams: central policy, audit and rotation, reached over the network. MoltenRock is a local vault for the Mac where your AI agents run: no server, no account, keys sealed in the Secure Enclave, released per agent, with Touch ID approval for changes through MoltenRock Connect. Use the cloud for production, and MoltenRock for the desktop agent.
The problem
Desktop agents fall between the cracks
- Built for serversPolicies and identities are designed for services and pipelines, not a person’s laptop agent.
- A service to runSomeone hosts it or subscribes to it, and every secret fetch crosses the network.
- No human gateAccess is automatic once policy allows it; there is no “ask me first” for a refund.
How MoltenRock handles it
Local by design
- On the MacThe vault is where the agent is. No network hop to fetch a key.
- Per-agent grantsGrants per agent and per key, with a log of every release.
- ApprovalsChanges through MoltenRock Connect wait for your Touch ID.
