Add the MCP config

Create or open .cursor/mcp.json in your project root and paste the Fast.io config. This registers 251 storage and AI tools.

Authenticate once

When Cursor first calls a storage tool, a browser window will open for you to sign in. Your credentials are stored securely for future sessions.

3

Start storing

Cursor can now upload assets, organize folders, and create share links. All files are available in your Fast.io dashboard for human review.

Professional workspaces for every project

FAQ

What is the Fast.io MCP server?

It's a server that provides Cursor with 251 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?

The first time Cursor uses a Fast.io tool, it opens a browser tab to sign in or create a free account. Your session persists, so there are no API keys to manage manually.

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 happens when I hit the credit limit?

You get 5,000 credits per month. When they run out, new uploads and AI queries pause until the next cycle. Existing files and share links 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.
