Add it in three steps

Grok Bot adds plugins from the Cursor Marketplace. Fastio's is one of them.

Step 1: Open the Fastio listing

The listing for Grok Bot is on x.ai. It shows the Fastio plugin and an Add to Grok Bot button.
Open the listing (opens in a new tab)
Step 2: Select Add to Grok Bot

The plugin brings two things to your Bots: the Fastio MCP server and the Fastio agent guide, a skill that tells a Bot how to use it.
Step 3: Give a Bot a Fastio task

Message a Bot with something to do in Fastio. The first time it uses Fastio, it asks you to sign in to Fastio.

Grok Bot is in beta on desktop (macOS and Windows) and iOS. Get Grok Bot (opens in a new tab)

Try these with a Bot

Once the plugin is added, message a Bot like a teammate. Use your own workspace, file and client names.

Writer Bot Edits the launch plan with the file locked
Research Bot Finds answers in your documents

What your Bots can do with Fastio

Your Bots share one cloud computer. A Fastio workspace is shared with the people the work is for: your team and your clients.

Shared workspace

Many Bots, one workspace

Give several Bots the same Fastio workspace and they work from one set of files. The people on your team see the same files, comments and activity.

A visible lock shows when a file is being edited
Comments are attached to files, for Bots and people alike
Version history keeps every version

Cited answers

Answers from your documents, with the source

Turn on Intelligence for a workspace and a Bot can ask Fastio about the files in it. Each answer cites the document it came from, and the page where one applies.

Search by keyword or by meaning
Pull the exact passage an answer rests on
Read and set file metadata

Branded shares

Send work to clients, and get theirs back

A Bot can create a branded share in Send, Receive or Exchange mode. The client opens it in a browser with no account, and what they upload lands in the share.

Send, Receive and Exchange modes
Password protection and expiration
Your logo on the share page

Handoff

Hand the finished work to a person

When the job is done, a Bot can transfer ownership of the organization it set up to a member you name. The new owner gets its workspaces, files and shares.

Ownership moves to a member of the organization
The activity log records the transfer
Everything stays open at go.fast.io

The same plugin in Cursor

Grok Bot adds Fastio's plugin from the Cursor Marketplace, so Cursor can use it too. Run this in Cursor's chat to add it.

FAQ

What is the Fastio plugin for Grok Bot?

It is the Fastio plugin from the Cursor Marketplace, which Grok Bot can add. It gives your Bots the Fastio MCP server, for files, shares, comments, metadata and AI search in your Fastio account, and the Fastio agent guide, a skill that tells a Bot how to use those tools.

How do I add Fastio to Grok Bot?

Open the Fastio listing for Grok Bot on x.ai and select Add to Grok Bot. Then message a Bot with a task for Fastio. The first time it uses Fastio, it asks you to sign in to Fastio.

Who can use Grok Bot?

Grok Bot is in beta. It runs on desktop (macOS and Windows) and iOS, for SuperGrok, SuperGrok Plus and Heavy subscribers and for Cursor Pro, Pro+, Ultra and Teams subscribers.

How does sign-in work?

The first time a Bot uses Fastio, it asks you to sign in to Fastio. The Fastio MCP server signs in with OAuth, so there is no API key to copy or store.

Can several Bots work in the same Fastio workspace?

Yes. Your Bots and the people you invite can work in the same workspaces. A visible lock shows when a file is being edited, comments are attached to files, and version history keeps every version.

Can a Bot answer questions about my documents?

Yes, once Intelligence is on for the workspace. A Bot can ask Fastio about the files in it, and each answer cites the documents it came from, with the page where one applies. Without Intelligence, search finds file names but not what is inside the files.

Can my Bots share files with people who don't use Grok Bot?

Yes. A Bot can create a branded share in Send, Receive or Exchange mode. Share links are regular web addresses, and recipients get previews, downloads and comments in a browser without needing an account.

Can I connect Grok to Fastio without Grok Bot?

Yes. Grok on the web can add Fastio as a custom connector at https://mcp.fast.io/mcp/tools, and the Grok CLI can add it from the /mcps menu at https://mcp.fast.io/mcp/code. Both sign in on Fastio's own page in your browser.
