Show HN: Secret MCP: Let AI write your .env files without seeing your secrets (github.com)

A new desktop application, Secret MCP, has been launched to enhance the way developers manage sensitive information by allowing AI coding assistants to generate .env files securely. The innovative MCP server acts as an intermediary, providing two key functions: `search_secrets`, which enables AI to find secrets by name or description without exposing the actual values, and `write_env`, which writes those secrets directly to .env files from local storage. This means developers can leverage AI’s coding capabilities without the risk of leaking sensitive data, as all values remain securely stored on the user's machine. Significantly, Secret MCP empowers developers to streamline their workflow while ensuring privacy. With secrets stored locally in an SQLite database and a simple interface for managing them, the tool integrates seamlessly into projects using Node.js and Tauri. By generating .env files with strict permissions, the app reinforces the critical importance of security in AI-assisted coding. The tool is easily accessible via an npm package, facilitating quick installation and integration into existing workflows, making it an invaluable asset for developers wary of exposing their credentials in cloud environments.
