Best File storage MCP servers

File-storage MCP servers connect an agent to the cloud drives where your documents actually live — searching, reading, uploading, and organizing files in Box, Dropbox, Google Drive, and similar platforms. The payoff is letting an agent work with real company documents in place: it can find the right contract, summarize a folder, pull a spreadsheet into context, or file a generated report back to the correct location without a human shuttling files around. When choosing, look at how the server scopes access (a whole account versus specific folders), whether it can read file contents or just metadata, and the auth model — these are almost all OAuth remote servers touching sensitive documents, so prefer least-privilege scopes and keep write and delete tools behind review.
