WHAT IT DOES

What mcp_flush_rewrite does on Wordpress

AI agents invoke mcp_flush_rewrite to trigger actions in Wordpress. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why mcp_flush_rewrite is rated High

Flushing rewrite rules triggers an external WordPress operation that regenerates the rewrite rules cache/database entry. It is not a simple read or data write — it executes a system-level action (wp_flush_rules) that rebuilds internal routing tables. Misuse could temporarily break site navigation, but it is reversible by re-flushing, making it Execute rather than Destructive.

RECOMMENDED RULE

The rule that runs mcp_flush_rewrite safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Wordpress, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mcp_flush_rewrite, this is the rule to start with:

mcp_flush_rewrite Rate-limited

mcp_flush_rewrite stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "max": 10,

      ]
    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect Wordpress, apply this rule, and every mcp_flush_rewrite call is checked against it from then on.
