Why word_moveCursor needs a policy

Moving the cursor in a Word document via COM Interop is an active operation that changes the state of the application (selection/cursor position), triggering external operations in the Word process. It doesn't read data or write/modify document content directly, but it executes a programmatic action within the Word COM interface that affects subsequent operations.

From the tool's definition Moves the cursor by the specified unit and count

POLICY

How to control word_moveCursor

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "word_moveCursor": {
      "limits": [
        {
          "counter": "word_movecursor_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

word_moveCursor 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.

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