Frequently asked questions

What is uldl?

Persistent file storage for AI agents via MCP and curl. Upload, download, and version files.

How do I install uldl?

It runs as a remote server. In Claude Code: claude mcp add --transport http uldl 'https://uldl.sh/api/mcp' --header 'Authorization: <Bearer access key (e.g. '\''Bearer your-access-key'\'')>' --header 'x-uldl-username: <Your uldl.sh username>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does uldl need an API key?

Yes. It expects Authorization, x-uldl-username, which you set in its configuration.

Who maintains uldl?

It is published by sh.uldl. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
