AI agents call get_alert_policy to retrieve information from Newrelic without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and returns information about an alert policy. This is a read-only operation with no side effects. It does not create, modify, delete, or execute anything. The blast radius of misuse is minimal—an attacker could only learn about existing alert policies, not cause harm through the tool itself.
From the tool's definition Tool name is 'get_alert_policy' and description states 'Get details for a specific alert policy' — this is a retrieval operation that queries existing alert policy configuration without modifying, deleting, or executing any actions.
Attacks that exploit this kind of access
Get details for a specific alert policy. It is categorised as a Read tool in the Newrelic MCP Server, which means it retrieves data without modifying state.
Register the Newrelic MCP server in PolicyLayer and add a rule for get_alert_policy: 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 Newrelic. Nothing to install.
get_alert_policy 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 get_alert_policy 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 get_alert_policy. 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.
get_alert_policy is provided by the Newrelic MCP server (@piekstras/newrelic-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
