Your coding agent needs access. Not your API key.

MetaVault OSS is a local, encrypted credential vault for AI coding agents. Store your credentials once instead of scattering live keys across chat prompts and .env files.

The agent requests a capability by alias, scope and reason. Deterministic policy rules check the request, and the local daemon performs the authorized call using the stored credential. The agent receives the result, not the raw key. Credentials are encrypted at rest with AES-256-GCM.

Meta Muse Spark adds a metadata-only risk review through the Warden. It can flag risk or recommend stricter handling, but it cannot override the hard policy rules. Approval happens locally when required, with scoped, revocable agent access and a local audit trail.

The vault, daemon, MCP server and approval interface run on your machine. The optional Muse Spark review calls Meta's API; credentials stay out of that review.

One local vault for your coding agents. Less .env clutter.
You know where the keys at. Always.
