Add FXI Studio to Grok
Grok lets you bring your own MCP server as a custom connector. Paste the FXI Studio server URL, sign in, and make images, video clips and whole scenes from a Grok chat.
Server URL
https://mcp.fxi.studio/mcpFXI Studio is not in Grok’s connector catalog. You add it yourself as a custom MCP connector with its server URL.
Step by step

Open Connectors
Go to grok.com/connectors while signed in to Grok.

https://mcp.fxi.studio/mcpSign in, then Allow
Complete the sign-in when Grok asks for it, or create a free FXI Studio account with 65 credits, then click Allow to let Grok use it. Grok then lists the FXI Studio tools.
Ask in a chat
Ask Grok for what you want. For example: make a still of a rain-soaked neon alley, then turn it into a slow dolly-in clip.
A Grok Bot that drives FXI Studio
For a shareable Grok Bot card, built on the always-on agent’s "Connect apps."
Open Connect apps
In your Grok Bot’s settings, open Connect apps and choose Custom MCP.
Add FXI Studio
Paste the FXI Studio server URL, sign in, then click Allow.
https://mcp.fxi.studio/mcpShare the Bot
Anyone who adds your Grok Bot can now ask it to make stills and clips through FXI Studio, each billed to their own FXI Studio account.
Grok Business and Enterprise
An admin provisions it
A team admin adds FXI Studio as a custom connector in the xAI cloud console, using the same server URL.
Members sign in
Once it is provisioned, FXI Studio is available to members, and each one signs in with their own FXI Studio account.
Building with the xAI API
For developers using remote MCP tools in the xAI API.
Create an FXI Studio API key
In FXI Studio, open Settings and create an API key. Treat it like a password.
Add FXI Studio as a remote MCP tool
Add this entry to the tools array of your request. The key goes in authorization, which xAI sends as the Authorization header.
{ "type": "mcp", "server_url": "https://mcp.fxi.studio/mcp", "server_label": "fxi_studio", "authorization": "YOUR_FXI_KEY" }
What you can do once Grok is connected
Make stills
Describe a frame and get a cinematic image back in the chat.
Make video clips
Turn a prompt or one of your stills into a short clip.
Chain shots
Frame chaining starts each clip from the last frame of the one before, so motion stays continuous.
Compose scenes
Hand over a brief and get a multi-shot scene planned and generated.
Use your characters
Reuse the characters and images saved in your FXI Studio account.
Keep everything
Every result saves to your FXI Studio library, ready to edit on the web.
Credits
New accounts start with 65 free credits, and free-plan credits refill weekly. Each generation uses credits from your FXI Studio account; the cost is checked before anything runs, and refused or failed requests are not charged. See plans and packs.
