THE RISK

Medium Risk

Why batch_add_items needs a policy

This tool creates or modifies data in OmniFocus (adding tasks/projects), which is reversible through deletion. It does not execute arbitrary code, delete data irreversibly, or move money. Multiple writes in one operation elevates severity from low to medium due to the potential to bulk-create unwanted items.

From the tool's definition Tool name 'batch_add_items' and description 'Add multiple tasks or projects to OmniFocus in a single operation' indicate creation of new data entries. The batch nature means multiple items are created simultaneously, increasing the blast radius if misused.

POLICY

How to control batch_add_items

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "batch_add_items": {
      "limits": [
        {
          "counter": "batch_add_items_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

batch_add_items stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

How do I enforce a policy on batch_add_items? +

Register the OmniFocus MCP Enhanced MCP server in PolicyLayer and add a rule for batch_add_items: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches OmniFocus MCP Enhanced. Nothing to install.

What risk level is batch_add_items? +

batch_add_items is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit batch_add_items? +
