WHAT IT DOES

What create_schema does on Amazon Location Service MCP Server

AI agents use create_schema 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 RISK

Medium Risk

Why create_schema needs a policy

Schema creation is a write operation that modifies data structures or configuration in a reversible manner. Without descriptive details, we assume standard schema creation behavior. Severity is medium because schema creation can impact system structure and data organization, but is typically reversible through deletion.

From the tool's definition Tool name is 'create_schema' which indicates creation of a new schema object. The description is empty, providing no additional context about scope or constraints.

Documented attack patterns abuse exactly the kind of access create_schema gives an agent:

POLICY

How to control create_schema

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_schema:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_schema": {
      "limits": [
        {
          "counter": "create_schema_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_schema 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.
