List available Datadog metrics, optionally filtered by a search query.
AI agents call list_metrics to retrieve information from MCP Datadog 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 queries available metrics from Datadog. It performs no modifications, deletions, code execution, or financial transactions. It is a straightforward informational read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states 'List available Datadog metrics, optionally filtered by a search query.' The verb 'list' and the read-only nature of metric enumeration indicate pure data retrieval with no side effects.
Attacks that exploit this kind of access
List available Datadog metrics, optionally filtered by a search query. It is categorised as a Read tool in the MCP Datadog Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Datadog Server MCP server in PolicyLayer and add a rule for list_metrics: 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 MCP Datadog Server. Nothing to install.
list_metrics 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 list_metrics 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 list_metrics. 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.
list_metrics is provided by the MCP Datadog Server MCP server (micaelmalta/mcp-server-datadog). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
