uldl is a Model Context Protocol (MCP) server: Persistent file storage for AI agents via MCP and curl. Upload, download, and version files. Because it speaks the Model Context Protocol, AI assistants can use uldl as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://uldl.sh/api/mcp and you're connected, with nothing to install locally. The current release is v0.1.0.
On mcp.site, uldl sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
