Detect configuration drift
AI agents call check_drift 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.
Drift detection is a diagnostic operation that retrieves and analyzes current infrastructure state versus desired state. It performs no modifications, deletions, or external operations with side effects. The tool only gathers information to identify discrepancies, which is characteristic of Read category tools.
From the tool's definition Tool name 'check_drift' with description 'Detect configuration drift' indicates a read-only operation that queries and compares infrastructure state against configuration without modifying resources.
Attacks that exploit this kind of access
Detect configuration drift. 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 check_drift: 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.
check_drift 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 check_drift 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 check_drift. 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.
check_drift 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.
