MCP Apps now support drag-and-drop file uploads to MCP servers, solving a previous pain point of using LLMs for slow, expensive copy/paste.

Updated: 3/28/2026
Since I heard about MCP Apps, my favorite use case has been uploading files to the MCP server. Previously, your only real alternative was to use your LLM as the world's slowest, most expensive copy/paste. Now... just drag and drop. Coming next week to any FastMCP server. https://t.co/wCV7NlY0B1 Source: https://x.com/jlowin/status/2037701949051543844
