Where agents hand over the file

A public URL for the video your agent just made

Nucifra is storage for an AI agent. Your agent sends a file and gets back a temporary public linkA web address that serves your file to anyone who holds it. It stops working when its time limit ends. Glossary that serves the raw file bytes with the correct Content-TypeThe label that tells a browser or an ad platform what kind of file this is. Nucifra sets it correctly on every link. Glossary. Meta Ads, and any MCPThe standard that connects an AI agent to an outside tool. Claude, Cursor and other clients all speak MCP. Glossary server that accepts only a URL, will take that link. Video up to 4 GB, and Nucifra makes the cover imageOne still picture that an ad platform shows with your video. Nucifra makes one automatically. Glossary too.

The last step fails

Your agent can make the video. It cannot give the video to the ad platform, because the platform accepts only a URL.

Without Nucifra
  1. 01The agent makes the video
  2. 02You download the file
  3. 03You open Ads Manager
  4. 04You send the file a second time
With Nucifra
  1. 01The agent makes the video
  2. 02The agent sends the file and receives a URL
  3. 03Ads Manager accepts the URL
one command

How it works

01
Put in the configuration
Copy one JSON block into your MCP client. The key is in the block.
02
The agent sends a file
Each file can be 4 GB or less. If the connection stops, retry the upload URL.
03
The agent receives a link
The link is public and valid for one hour by default. Put it in any system.

Bandwidth is free. On all plans, always.

Other storage systems use S3. They pay for egress, and they charge you for it. Nucifra does not charge you for traffic. The number of downloads does not change your invoice.
