What create_api does on Amazon Location Service MCP Server

AI agents use create_api 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.

Medium Risk

Why create_api needs a policy

API creation is a reversible write operation that modifies AWS infrastructure. It creates a new resource without permanent deletion, fitting the Write category. Severity is medium because misconfigured APIs could expose services or create unexpected costs, but the blast radius depends on subsequent configuration.

From the tool's definition Tool name 'create_api' indicates creation of an API resource. Description is empty, limiting direct evidence, but the name strongly suggests a write operation that creates a new AWS API resource (likely API Gateway or similar).

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

How to control create_api

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_api:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_api": {
      "limits": [
        {
          "counter": "create_api_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_api 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.

  1. Create a free account and register Amazon Location Service MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
