THE RISK

Low Risk

Why get_case_stages needs a policy

This tool queries and returns case stage metadata without creating, modifying, deleting, or executing any operations. It has no side effects beyond retrieving information about an existing case's workflow stages. The blast radius of misuse is minimal—an agent could only access information it is already authorized to see in the Pega platform.

From the tool's definition Tool name 'get_case_stages' and description 'Retrieve the stages list for a given case ID with processes, steps, and visited status information' indicate data retrieval only.

POLICY

How to control get_case_stages

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

policy.json

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

get_case_stages 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 Pega DX 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.
