Returns a list of Timestream for InfluxDB DB instances filtered by status (case-insensitive).
AI agents call LsInstancesByStatus 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.
This tool queries and lists database instances based on status criteria. It performs no mutations, deletions, or external operations—only data retrieval. The filtering is applied to existing data. The blast radius of misuse is minimal: an attacker could enumerate database instances but cannot modify, delete, or access their contents through this tool alone.
From the tool's definition Tool name 'LsInstancesByStatus' and description 'Returns a list of Timestream for InfluxDB DB instances filtered by status' indicate a read-only query operation that retrieves and filters existing data without modification.
Documented attack patterns abuse exactly the kind of access LsInstancesByStatus 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 LsInstancesByStatus:
{
"version": "1",
"default": "deny",
"tools": {
"LsInstancesByStatus": {}
}
}LsInstancesByStatus is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns a list of Timestream for InfluxDB DB instances filtered by status (case-insensitive). 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 LsInstancesByStatus: 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.
LsInstancesByStatus 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 LsInstancesByStatus 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 LsInstancesByStatus. 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.
LsInstancesByStatus 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.
