Factorly is a local proxy runtime that secures API keys and credentials when AI agents call external tools, by injecting secrets from an encrypted vault, enforcing governance rules, and logging all activity. It combines credential security, tool orchestration, and oversight in a single configurable system, making it a practical solution for safely integrating AI agents with REST APIs, CLIs, and MCP servers.

Target audience: backend devs, devops, ai engineers
