Smart Drive is cloud storage built for AI agents, not just for people. A REST API and an MCP server (@aiinak/workspace-mcp) let Claude, Cursor or your own scripts search your drive by meaning, read docs, sheets and PDFs as extracted text, upload files and share them. Everything an agent creates shows up instantly in your Drive. Personal API keys are scoped and revocable, every call is logged, and agent uploads share your quota, so there is no separate agent storage to manage. 50GB free.
