Filesystem MCP Server

Give your AI the power to read, write, convert, and analyze files in an isolated sandbox, through one hosted MCP server you do not have to install or run. UniversalBench is the server: connect one URL and your AI gets Filesystem plus every other capability, with safety built in. Works with Claude, ChatGPT, Gemini, and any MCP-compatible AI.

It is a hosted MCP server, so there is nothing to install, nothing to keep running, and the same single connection also covers databases, code, web search, GitHub, files, and more.
