Compare current permissions against required permissions for specific operations and identify gaps
AI agents call gcp-iam-analyse-permission-gaps to retrieve information from GCP Billing and Monitoring MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes permission data to highlight discrepancies between actual and required permissions. It is fundamentally a read operation that queries IAM state without side effects. While permission analysis could inform security decisions, the tool itself performs no write, destructive, execute, or financial operations.
From the tool's definition Tool performs comparison and analysis of permissions ('Compare current permissions against required permissions') to 'identify gaps'.
Attacks that exploit this kind of access
Compare current permissions against required permissions for specific operations and identify gaps. It is categorised as a Read tool in the GCP Billing and Monitoring MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GCP Billing and Monitoring MCP Server MCP server in PolicyLayer and add a rule for gcp-iam-analyse-permission-gaps: 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 GCP Billing and Monitoring MCP Server. Nothing to install.
gcp-iam-analyse-permission-gaps 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 gcp-iam-analyse-permission-gaps 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 gcp-iam-analyse-permission-gaps. 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.
gcp-iam-analyse-permission-gaps is provided by the GCP Billing and Monitoring MCP Server MCP server (radiumgu/gcp-billing-and-monitoring-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
