Getting started

Nucifra is object storage for an AI agent. The agent sends a file. Nucifra returns a public link. You put the link in a system that accepts only a URL, such as Meta Ads Manager.

What you need

  • An MCP client. Claude Desktop, Claude Code, Claude.ai, Cursor, and any Streamable HTTP client all work.
  • A Nucifra account. Sign up at nucifra.com with Google or GitHub. No payment card.

The two steps

  1. Put the Nucifra server in your client’s configuration. Each client stores this in a different place. See the page for your client in this section.
  2. Start the client again, or reconnect. The agent asks you to sign in on its first tool call. Sign in takes two clicks.

After that, tell the agent what to do in plain language:

upload creative_v3.mp4 to nucifra.
give me the public link

The agent calls nucifra_create_upload_url, uploads the file straight to storage, then calls nucifra_create_public_url. You never handle the file yourself.

The four tools

Tool What it does
nucifra_create_upload_url Mints a short-lived upload link for one file.
nucifra_create_public_url Confirms the file arrived and mints a public link to it.
nucifra_list_objects Lists the files the agent has already sent.
nucifra_delete_object Removes one file.

Example prompts

Use these to test a new connection, one per tool:

“Upload frame.png and give me a public link.” Calls nucifra_create_upload_url, then nucifra_create_public_url.

“Make a fresh link for creative_v3.mp4. The old one expired.” Calls nucifra_create_public_url again for a file already stored.

“What files do I have in Nucifra right now?” Calls nucifra_list_objects.

“Delete draft_v1.mp4. I do not need it anymore.” Calls nucifra_delete_object.
