AI agents use create_datastore 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.
The 'create_' prefix indicates a write operation that creates new data structures. In AWS Location Service, a datastore is a reversible resource creation (can be deleted). However, creating a datastore could enable unauthorized location data storage or access, warranting medium severity. Confidence is moderate due to missing description and reliance on name and server context alone.
From the tool's definition Tool name 'create_datastore' and prefix pattern 'create_' strongly suggest data creation. Server context is AWS Location Service, where datastores hold geospatial/location data. Empty description limits certainty.
Documented attack patterns abuse exactly the kind of access create_datastore 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 create_datastore:
{
"version": "1",
"default": "deny",
"tools": {
"create_datastore": {
"limits": [
{
"counter": "create_datastore_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} create_datastore 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.

create_datastore. 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 create_datastore: 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.
create_datastore 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 create_datastore 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 create_datastore. 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.
create_datastore 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.
