secretctl MCP Server

Example Use Cases

• 1

  Run commands with injected secrets without exposing plaintext credentials.

• 2

  Securely list and verify secrets metadata without accessing secret values.

• 3

  Execute commands with automatic output sanitization to prevent secret leakage.

Description

secretctl MCP server provides a secure interface for AI coding assistants like Claude Code to run commands with injected secrets as environment variables, ensuring that AI agents never see plaintext secrets. It supports multiple tools for secret management, command execution with secret injection, and enforces policy controls to prevent secret exposure. This approach enhances security by following an 'Access Without Exposure' philosophy, combining AES-256-GCM encryption, Argon2id key derivation, and output sanitization to protect sensitive data.
