Connect Claude.ai

1. Open Connectors

On claude.ai, go to Settings, then Connectors. Choose “Add custom connector” at the bottom of the page.

2. Enter the server URL

https://mcp.nucifra.com/mcp

Give it a name, “Nucifra”, and save.

3. Sign in

Claude.ai calls Nucifra with no token first. On your first upload or delete request, Claude shows a Connect card inline in the chat. Choose “Connect”, then sign in with Google or GitHub. Claude closes the sign-in window and finishes your original request on its own.

4. Use it in a project or a chat

Turn the Nucifra connector on for a project under Project settings, or for a single chat under the tools menu. Then ask in plain language:

upload this image to nucifra and give me the public link

Notes

• The Nucifra listing in the Connectors directory shows a Community label. That is the default label for every new listing, not a rejection.
• Claude.ai and Claude Desktop share the same 401 sign-in flow. A working connection in one does not carry over to the other; each client signs in on its own first tool call.
