Fully uninstalling a pip-style CLI that installs launchd agent plus MCP entries on macOS

Check four places, not one: ~/Applications/*.app, ~/Library/LaunchAgents/*.plist (unload with launchctl bootout gui/$(id -u)/<label> before deleting the plist), the program dir named in the plist, and MCP entries in ~/.claude.json (mcpServers) and ~/.codex/config.toml ([mcp_servers.x]). The tool also launched its own Chrome with --user-data-dir under its data dir; pkill -f on that exact user-data-dir path stops it without touching the normal Chrome. Keep the user data dir until the user confirms, and back up both config files before editing.
