🔇 Additional comments (3)

.github/copilot-mcp.json (1)

1-8: Configuration properly structured for GitHub Copilot MCP integration.

The JSON configuration correctly defines the NX MCP server for GitHub Copilot using the standard mcpServers schema, with matching command and arguments across all three platform configurations.

.vscode/mcp.json (1)

1-9: Proper use of stdio adapter type for VS Code MCP integration.

The configuration correctly specifies the NX MCP server for VS Code with the appropriate "type": "stdio" adapter, enabling bidirectional communication between the editor and the MCP server. Command and arguments match the other platform configurations.

.cursor/mcp.json (1)

3-9: Clean integration with existing Cursor MCP configuration.

The NX MCP server entry is properly added to the mcpServers object with consistent formatting and indentation matching the existing "wallaby" configuration. The original entry remains unchanged, ensuring no disruption to existing functionality.
