Remove members by rank range.
AI agents use sorted_set_remove_by_rank to create or update resources in Amazon Location Service MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon Location Service MCP Server environment.
This tool removes/deletes members from a sorted set, which constitutes a data modification. While 'remove' suggests deletion, in the context of sorted sets (Redis-like data structures), removing members is a reversible operation if the original data can be restored from backups or if the operation is within a transaction that can be rolled back.
From the tool's definition Tool description: 'Remove members by rank range.' This performs a removal operation on a sorted set data structure, which modifies data by deleting specific members based on their rank position.
Documented attack patterns abuse exactly the kind of access sorted_set_remove_by_rank 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 sorted_set_remove_by_rank:
{
"version": "1",
"default": "deny",
"tools": {
"sorted_set_remove_by_rank": {
"limits": [
{
"counter": "sorted_set_remove_by_rank_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} sorted_set_remove_by_rank stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Remove members by rank range. It is categorised as a Write tool in the Amazon Location Service MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Amazon Location Service MCP Server MCP server in PolicyLayer and add a rule for sorted_set_remove_by_rank: 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.
sorted_set_remove_by_rank is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the sorted_set_remove_by_rank 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 sorted_set_remove_by_rank. 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.
sorted_set_remove_by_rank 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.
