Passwd.page is a zero-knowledge secret sharing tool that encrypts secrets client-side and self-destructs after one read, supporting humans and AI agents via browser, CLI, and MCP protocol. It stands out for its MCP server integration, making it easy to securely hand secrets to AI agents without exposing them in prompts, and offers a single self-hostable binary for privacy-conscious teams.

Target audience: backend devs, devops, security engineers
