Initializes the Application Design Center environment. This is a one-time setup step that must be performed before other ADC tools can be used.
manage_application
Manages the deployment lifecycle of an application. Use this tool to deploy a verified design using the Application Design Center or retrieve the status and details of an existing deployment. This is the final step that turns your design into a deployed infrastructure on Google Cloud.
manage_application_template
Manages the Infrastructure as Code (IaC) content of your infrastructure design. Use this to save the design as an Application Design Center template, export the design as Terraform files, or update the design (e.g. component, parameters configurations etc).
assess_best_practices
Performs a comprehensive security and configuration audit on your application design before deployment. It validates the design against Security Command Center frameworks and relevant controls, returning a report with actionable findings for remediation.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Gemini Cloud Assist MCP is categorized under Cloud Platforms and uses a remote streaming HTTP/SSE transport. In contrast, Arcane RMCP belongs to Cloud Platforms using local stdio subprocess. Select Gemini Cloud Assist MCP when you need capabilities focused on cloud platforms and Arcane RMCP when you require tools for cloud platforms.
