MoltenRock vs .env files for AI agents
.env files were made for apps you wrote, on servers you run. AI agents read files for a living. That changes the risk.
The short answer
A .env file stores API keys in plain text; any process on the Mac, and any coding agent working in that folder, can read it, and it is easy to commit or sync by mistake. MoltenRock keeps keys in a Secure Enclave vault and releases them only to the agent you granted, logging each release. For agents, that is the difference between “anyone who looks” and “only who you chose”.
The problem
Why .env and agents don’t mix
- Plain textNo encryption, no access control beyond file permissions.
- Agents read the folderCoding agents open files to understand a project; .env files are files.
- Copied everywhereBackups, sync folders, zip files, accidental commits.
How MoltenRock handles it
What a vault changes
- Encrypted and sealedSecure Enclave protection and encryption at rest.
- Granted, not foundAn agent gets a key because you granted it, not because it opened a file.
- LoggedEvery release and denial is recorded.
Side by side
.env files vs MoltenRock
| MoltenRock | .env file | |
|---|---|---|
| Storage | Secure Enclave vault, encrypted at rest | Plain text on disk |
| Who can read a key | Only agents you granted | Any process or agent with file access |
| Record of use | Activity log per agent | None |
| Revoking one agent | One switch | Rotate the key everywhere |
| Accidental commit | Nothing to commit | A common leak |
| Works for any script | No: keys go to OpenClaw and Hermes; other tools use Connect | Yes |
Straight answer: .env files are still the simplest option for your own app code. MoltenRock is built for AI agents.
Straight answer
When to keep your .env
Stays on your Mac
- Keys your agents use, in the vault
- A record of each release
- Keys for tools on MoltenRock Connect: they never need one
Leaves your Mac
- A key to OpenClaw or Hermes, when granted
- Your own app’s runtime config, which can stay in .env for now
- Nothing to a MoltenRock server
Questions
What people ask first
How do my .env keys get into MoltenRock?
Paste each key once; it is sealed as it goes in. Then delete it from the .env file.
Does Claude Code need my .env?
Not for business platforms: it can reach them through MoltenRock Connect over MCP without keys. Keep secrets out of folders an agent works in.
Is a .env in .gitignore safe?
Safer, but still plain text on disk and readable by anything that opens the folder, including agents.
What does it cost?
MoltenRock is free with 3 keys; Pro is unlimited from $9.99 a month.
Take the keys out of the folder.
Free for Mac. No account, no cloud, no telemetry.
