MCP Server Installation - Login Mode (With API Key)

February 12, 2026 ยท View on GitHub

This document provides the configuration-only method for installing the @syncause/debug-mcp MCP server. This mode requires a API_KEY for authentication.

You should modify the configuration file for your specific IDE. Project-level configuration is recommended where available.

If you can't modify the configuration file, you MUST output the instructions to the user, instead of letting the user read this document.
