Fast.io MCP Server

Store files. Share with humans. Query with AI. All through one API -- free.

This is a summary. The complete agent guide with all 257 tool parameters, workflows, ID formats, and constraints is at https://mcp.fast.io/skill.md -- fetch it at the start of every session.

Fast.io gives AI agents a complete file management and collaboration platform. Upload outputs, create branded data rooms, ask questions about documents using built-in AI, and hand everything off to a human when the job is done.
