Why preview_bulk_delete needs a policy

This tool only previews/displays which forms would be affected by a bulk delete operation. It performs no actual deletion or modification — it is a read-only safety check. The description explicitly states it shows what 'would be deleted' before the actual operation, making it a pure read/query tool.

From the tool's definition SAFETY PREVIEW: Show exactly which forms would be deleted before bulk deletion - USE THIS FIRST to confirm what will be deleted

How to control preview_bulk_delete

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

policy.json

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

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