WHAT IT DOES

What sync_check does on WP Astro MCP

AI agents call sync_check to retrieve information from WP Astro MCP 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 sync_check needs a policy

sync_check retrieves and compares data between WordPress and local exports to report differences. It has no side effects—it neither modifies files, executes external operations, deletes data, nor commits financial transactions. The dry-run guarantee and reporting-only nature confirm this is a Read operation with low blast radius.

From the tool's definition Tool is explicitly described as 'Dry-run only — no files are modified.' It 'compares' and 'reports' on WordPress content and local files, performing read-only operations to detect new, updated, or deleted posts.

POLICY

How to control sync_check

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

policy.json

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

sync_check 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 WP Astro MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
