Why archive_contact needs a policy

This tool modifies contact data by changing the ContactStatus field to ARCHIVED, which is a reversible state change (contacts can be unarchived). It does not delete data or cause irreversible destruction—history is preserved and the action can be undone. This qualifies as Write rather than Destructive.

From the tool's definition Archive a Xero contact by setting ContactStatus=ARCHIVED. Archived contacts are hidden from default lists but history is preserved.

POLICY

How to control archive_contact

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for archive_contact:

policy.json

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

archive_contact 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 Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
