AI agents call get_metric_data to retrieve information from Amazon Location Service MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name 'get_metric_data' follows standard AWS API patterns for retrieving monitoring metrics. The 'get_' prefix universally denotes read operations that query existing data without side effects. Even without a detailed description, this naming pattern reliably indicates a Read category operation. No evidence of data modification, deletion, code execution, or financial impact.
From the tool's definition Tool name 'get_metric_data' indicates retrieval of metric data without modification. Description is empty, limiting direct confirmation, but the naming convention strongly suggests a read-only query operation typical of AWS CloudWatch or monitoring APIs.
Documented attack patterns abuse exactly the kind of access get_metric_data gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Location Service MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_metric_data:
{
"version": "1",
"default": "deny",
"tools": {
"get_metric_data": {}
}
} get_metric_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_metric_data. It is categorised as a Read tool in the Amazon Location Service MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon Location Service MCP Server MCP server in PolicyLayer and add a rule for get_metric_data: 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 Amazon Location Service MCP Server. Nothing to install.
get_metric_data 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_metric_data 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_metric_data. 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_metric_data is provided by the Amazon Location Service MCP Server MCP server (awslabs.aws-location-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Amazon Location Service MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
