Fast.io MCP Server

Fast.io is an AI-first file sharing and collaboration platform. The Fast.io MCP server exposes 251 tools through a single remote endpoint, giving AI agents the ability to:

• Store and manage files — upload, download, move, copy, rename, and organize files and folders across workspaces and shares
• Share with branding — create branded share links with custom domains, logos, and access controls
• Collaborate — add comments, assign tasks, run approval workflows, and track activity via worklogs
• Use built-in RAG — query documents with AI-powered retrieval, generate shareable summaries, and run document analysis without bolting on a separate vector database
• Interact visually — render interactive UI widgets (file picker, viewer, uploader, workflow board, comments panel) directly in the agent chat
