gcp-trace-list-traces. 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-trace-list-traces: 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-trace-list-traces 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-trace-list-traces 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-trace-list-traces. 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-trace-list-traces 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.
