Draw a visual resource tree using Terragrunt CLI redesign commands
AI agents call draw_resource_tree to retrieve information from Terragrunt GCP Tool MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays the structure of cloud resources in a visual format. It performs introspection and visualization of existing infrastructure state without creating, modifying, deleting, or executing operations. The 'redesign commands' referenced are informational CLI operations for rendering resource topology.
From the tool's definition Tool name is 'draw_resource_tree' and description states it 'Draw[s] a visual resource tree using Terragrunt CLI redesign commands'.
Attacks that exploit this kind of access
Draw a visual resource tree using Terragrunt CLI redesign commands. It is categorised as a Read tool in the Terragrunt GCP Tool MCP MCP Server, which means it retrieves data without modifying state.
Register the Terragrunt GCP Tool MCP server in PolicyLayer and add a rule for draw_resource_tree: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Terragrunt GCP Tool MCP. Nothing to install.
draw_resource_tree is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the draw_resource_tree rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for draw_resource_tree. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
draw_resource_tree is provided by the Terragrunt GCP Tool MCP server (spolspol/terragrunt-gcp-tool-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
