WHAT IT DOES

What json_objkeys does on Amazon Data Processing MCP Server

AI agents call json_objkeys to retrieve information from Amazon Data Processing MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why json_objkeys needs a policy

This tool performs a simple query/retrieval operation to extract object keys from a JSON structure at a specified path. It has no side effects, cannot modify data, and presents minimal security risk even if misused by an AI agent. The operation is informational only.

From the tool's definition Tool name 'json_objkeys' and description 'Get the keys in the object at path' indicate a read-only operation that retrieves metadata about a JSON object structure without modifying, deleting, or executing code.

POLICY

How to control json_objkeys

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Data Processing MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for json_objkeys:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "json_objkeys": {}
  }
}

json_objkeys is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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