Why get-publishers needs a policy

This tool retrieves information about publishers without modifying, deleting, or executing any operations. It is a straightforward read operation that queries metadata about existing publishers in the PowerPlatform environment.

From the tool's definition Tool name 'get-publishers' and description 'Get all non-readonly publishers in the PowerPlatform environment' indicate a query/retrieval operation with no modification or deletion of data.

POLICY

How to control get-publishers

PolicyLayer is an MCP gateway — it sits between your AI agents and PowerPlatform MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get-publishers:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-publishers": {}
  }
}

get-publishers 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 PowerPlatform MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
