Archive a Xero contact by setting ContactStatus=ARCHIVED. Archived contacts are hidden from default lists but history is preserved.
AI agents use archive_contact to create or update resources in Mcp Afip — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Afip environment.
This tool modifies contact data (changes status field) but does not irreversibly delete information. Archiving is a reversible write operation that changes visibility and organization of records without destroying them. While the tool operates on financial/tax records (AFIP context), it does not move money or create financial obligations, so it does not qualify as Financial.
From the tool's definition Tool description states 'Archive a Xero contact by setting ContactStatus=ARCHIVED.' This is a state modification operation that changes the ContactStatus field of a contact record.
Documented attack patterns abuse exactly the kind of access archive_contact gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Afip, and nothing reaches the server without passing your rules. This is the rule we recommend for archive_contact:
{
"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.

Archive a Xero contact by setting ContactStatus=ARCHIVED. Archived contacts are hidden from default lists but history is preserved. It is categorised as a Write tool in the Mcp Afip MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Afip MCP server in PolicyLayer and add a rule for archive_contact: 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 Mcp Afip. Nothing to install.
archive_contact is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the archive_contact rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for archive_contact. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
archive_contact is provided by the Mcp Afip MCP server (codespar/mcp-dev-latam). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Afip, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
