@followed by the MCP server name and your instructions, e.g., "@io.github.sadri-dridi/open-agent-utility-indexwhat's the current UTC time?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Open Agent Utility Index
A local MCP plugin. It answers UTC time, JSON validity, URL host/path shape, and IANA timezone names. Tools run on your machine. They do not send requests, identifiers, or file contents anywhere.
Install
Cursor Directory and Cursor Marketplace install from this repository. After install, Cursor starts:
