Additional notes

The previous issues with Claude and Open Code weren't available so I had no idea if there was an actual endpoint for Cursor to find for the MCP server.

Code Review

This pull request adds a new "Cursor" configuration section to the MCP_USAGE.md documentation, detailing the configuration file paths and providing a JSON snippet for integration. The review feedback points out a typo ("you system's" instead of "your system's") and incorrect configuration file paths for Cursor on Windows and macOS/Linux.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

There is a typo in this line: "you system's" should be "your system's".

Suggested change

	To use this AI integrated MCP client, add the configuration snippet below to you system's `mcp.json` file.
	To use this AI integrated MCP client, add the configuration snippet below to your system's `mcp.json` file.

The configuration file paths for Cursor contain a few issues:

1. On macOS/Linux, the path is ~/.cursor/mcp.json (a directory named .cursor containing mcp.json), not ~/.cursor.json.
2. On Windows, the directory is typically lowercase .cursor rather than .CURSOR.
3. There is a missing colon after macOS/Linux.

Suggested change

	- **Windows:** `%USERPROFILE%\.CURSOR\mcp.json`
	- **macOS/Linux** `~/.cursor.json`
	- **Windows:** `%USERPROFILE%\.cursor\mcp.json`
	- **macOS/Linux:** `~/.cursor/mcp.json`

Review: ⚠️ Needs fixes

Thanks for the contribution! A couple of issues to fix before merging:

1. Typo: "you system's" → "your system's" in the Cursor intro paragraph
2. Wrong macOS/Linux path: ~/.cursor.json should be ~/.cursor/mcp.json. Cursor's MCP config file is ~/.cursor/mcp.json on both macOS and Linux, not .cursor.json.

Could you please fix both and push an update?
