Features

01Local Encrypted Credential Vault: Stores sensitive data (passwords, API keys, SSH keys, TOTP) locally, encrypted with XChaCha20-Poly1305, without requiring a cloud account.
02AI Agent Credential Relay (MCP Server): Functions as a local stdio MCP server, allowing AI agents to perform authenticated actions without exposing plaintext secrets to the model context.
03Flexible Credential Item Modules: Supports customizable credential items by combining various modules (username, password, API key, SSH key, TOTP, host, URL, custom fields).
04Cross-Platform & Portable: Available on Windows, macOS, and Linux, with portable builds and no installation/registration required.
05Diverse Credential Actions: Enables agents to perform actions like browser field filling, SSH command execution/file transfer, and authenticated HTTP requests.

Use cases

↳Automate Server Operations: AI agents can securely connect to servers via SSH to deploy builds or verify services using saved credentials.
↳Integrate with Authenticated APIs: Agents can make authenticated API calls (e.g., to DNS providers) without exposing API keys directly.
↳Streamline Browser Sign-ins: Automate browser login processes by having agents use saved credentials to fill form fields and submit them.
↳Secure Terminal Command Execution: Allow agents to run local or remote terminal commands with hidden modules substituted for sensitive arguments.
↳Managed File Transfers: Agents can securely upload or download files and directories over SFTP using their saved SSH identities.
