THE RISK

Why metadata-collection needs a policy

The tool only retrieves and returns metadata about collections. It performs a read-only operation with no side effects, modifications, or deletions. The word 'returns' clearly indicates a data retrieval operation.

From the tool's definition 'returns collections metadata with collection and description'

Documented attack patterns abuse exactly the kind of access metadata-collection gives an agent:

POLICY

How to control metadata-collection

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "metadata-collection": {}
  }
}

metadata-collection 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 Prime MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
