Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In the latest versions of the Cursor app, the command field in the beforeMCPExecution JSON payload no longer contains the expected command. Instead, it now contains the key used in the MCP JSON for that server. This change breaks functionality that relies on the command field.

Steps to Reproduce

run mcp when hooks configured on cursor app latest version on mac

Operating System

MacOS
