Authorizer is an open-source sign-in and access control server that adds AI-aware permission checks so assistants can verify whether a user may access a document before retrieval. It supports many login methods, multiple databases, and embeds OpenFGA plus a local MCP server to enforce fine-grained access control for teams using AI with company files. #Authorizer #OpenFGA #MCP
