FAQ
What is the Fastio MCP server?
It's a server that provides Cursor with a consolidated set of workspace tools. By adding it to your project config, Cursor can upload files, create share links, and query documents using RAG.
How does authentication work?
Cursor signs in to Fastio in your browser the first time it connects. On the Review Permissions screen you choose Read Only or Read & Write and which workspaces Cursor can reach, so there is no API key to create or store.
Can I see what Cursor uploads?
Yes. Everything Cursor stores is accessible at app.fast.io. You can browse, preview, comment on, and download files from any device.
Is this per-project or global?
The MCP config lives in .cursor/mcp.json in your project root, so each project can have its own setup. You can also share the config across projects by copying the file.
What are the usage limits on the plans?
Fastio starts with a 30-day Business Trial. Our Starter plan ($9.99/mo) includes 250 GB storage and 100,000 credits/mo. Business ($49.99/mo) includes 5 TB storage and 600,000 credits/mo. Enterprise ($199.99/mo) includes 25 TB storage and 3,000,000 credits/mo. Existing files and share links always remain accessible.
Can Cursor share files with people who don't use Cursor?
Yes. Share links are regular web URLs. Recipients open them in a browser and get previews, downloads, and commenting features without needing an account.
Cursor's integrated terminal can run fastio commands directly.
The Fastio CLI gives you the same workspace tools — upload,
search, share — as a standalone command. It also includes a
built-in MCP server via fastio mcp.
npm install --global @vividengine/fastio-cli
