Get transaction traces from APM, optionally filtering for slow transactions.
AI agents call get-transaction-traces to retrieve information from New Relic 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 APM transaction trace data without side effects. It performs a read-only query operation against New Relic's APM data store. Filtering for slow transactions is a query parameter adjustment, not a mutative action. The operation has minimal blast radius—it cannot modify monitoring data, execute arbitrary code, or affect system state.
From the tool's definition Tool name 'get-transaction-traces' and description 'Get transaction traces from APM' indicate data retrieval with 'optionally filtering' for view refinement. No modification, deletion, or code execution capabilities described.
Attacks that exploit this kind of access
Get transaction traces from APM, optionally filtering for slow transactions. It is categorised as a Read tool in the New Relic MCP Server MCP Server, which means it retrieves data without modifying state.
Register the New Relic MCP Server MCP server in PolicyLayer and add a rule for get-transaction-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 New Relic MCP Server. Nothing to install.
get-transaction-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 get-transaction-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 get-transaction-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.
get-transaction-traces is provided by the New Relic MCP Server MCP server (xelber/newrelic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
