enigmagent-mcp

A local encrypted vault MCP server that stores secret values using an Argon2id-derived AES-256-GCM key. It keeps the vault file encrypted at rest and resolves placeholders at runtime, ensuring LLMs never see real API keys. It supports stdio and REST transports with specific security boundaries.
