Frequently Asked Questions (FAQ) - Google Apps Script MCP Server

Q: What is an MCP Server? A: MCP stands for Model Context Protocol. An MCP server acts as a bridge, allowing AI models to access and interact with external data sources and tools in a standardized way.

Q: What is the Google Apps Script MCP Server? A: It’s a tool that allows you to manage Google Apps Script projects, deployments, and executions through any MCP-compatible client like Claude Desktop, VS Code with Cline, or Postman.

Q: What are the prerequisites for using this MCP Server? A: You need Node.js (v18+), npm, a Google Account with access to Google Cloud Console, and Git.

Q: How do I set up the Google Cloud OAuth? A: You need to create a Google Cloud Project, enable the Google Apps Script API, configure the OAuth consent screen, create OAuth 2.0 credentials, and configure environment variables. Detailed steps are in the documentation.

Q: What is OAuth 2.0 and why is it needed? A: OAuth 2.0 is an authorization framework that enables secure delegated access. The Google Apps Script MCP Server uses it to securely access Google Apps Script resources on your behalf, without requiring you to share your Google account password.

Q: How do I run the OAuth setup? A: Run npm run setup-oauth in your terminal. This will open your browser, prompt you to grant permissions, and securely store your OAuth tokens.

Q: What if I get a “Command not found” error? A: Ensure Node.js is properly installed and in your PATH. Use absolute paths to the Node.js executable if necessary.

Q: What do I do if I get an OAuth authentication error? A: Verify your OAuth credentials in the .env file, ensure environment variables are set correctly, and re-run the OAuth setup.

Q: How can I test if the MCP server is working? A: Run npm start and check for the message “Server ready to handle MCP requests”. You can also use npm run test-oauth to test OAuth authentication.

Q: What are the available tools provided by this MCP server? A: The server provides 16 tools for project management, version control, deployment management, script execution, and monitoring. Refer to the documentation for details.

Q: How do I update the server? A: To update the server, pull the latest changes from the repository and run npm install.

Q: What if I have multiple Google accounts? A: Ensure you’re selecting the correct Google account (the test user you added) during the OAuth authentication process.

Q: Where are the OAuth tokens stored? A: Tokens are stored securely in your operating system’s credential store (Windows Credential Manager, macOS Keychain Access, or Linux Secret Service API).

Q: How do I configure the MCP Server to work with Claude Desktop? A: Add the MCP server configuration to Claude Desktop’s claude_desktop_config.json file, including the correct paths to Node.js and mcpServer.js.

Q: How do I configure the MCP Server to work with VS Code? A: Install the Cline extension and add the MCP server configuration to your VS Code settings.json file.

Q: Where can I find help if I run into issues? A: Refer to the troubleshooting section in the documentation, check GitHub Issues, or join the #mcp-lab channel in the Postman Discord.

Q: How do I monitor the server in production? A: Use PM2 process manager or Docker to run the MCP server in production. This ensures auto-restart on system boot and provides monitoring capabilities.
