AI agents call get_server 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.
This tool retrieves server details without modifying, executing operations on, or deleting any data. It is a simple informational query with no side effects. Severity is low because disclosing server details has limited blast radius compared to write, execute, or destructive operations.
From the tool's definition Tool name 'get_server' and description 'Get details for a specific server' indicate a read-only retrieval operation. The verb 'Get' and lack of any modification language confirm this is a query operation.

Get details for a specific server. 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_server: 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_server 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_server 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_server. 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_server 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.
