FAF (Foundational AI-context Format) is an IANA-registered open format for persistent AI context. It transforms project metadata into structured YAML that AI tools can instantly understand, eliminating the need to re-explain projects. With 50,000+ downloads and multiple MCP integrations, FAF is a universal standard for AI context across different platforms.
