Create a new product (item) in the shop. Expects full item payload per Shopee /product/add_item spec (category_id, item_name, description, price+stock via model list or tier_variation, image.image_id_list, weight, logistic_info, etc.).
AI agents use add_item 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 creates new product records in a shop inventory system, which is a reversible write operation. While it modifies e-commerce data, it does not delete, move money, or execute arbitrary code. The blast radius is limited to product catalog management—new items can be edited or removed later.
From the tool's definition Creates a new product (item) in the shop with full item payload including category_id, item_name, description, price, stock, images, weight, and logistic information.
Documented attack patterns abuse exactly the kind of access add_item 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 add_item:
{
"version": "1",
"default": "deny",
"tools": {
"add_item": {
"limits": [
{
"counter": "add_item_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_item 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 new product (item) in the shop. Expects full item payload per Shopee /product/add_item spec (category_id, item_name, description, price+stock via model list or tier_variation, image.image_id_list, weight, logistic_info, etc.). 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 add_item: 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.
add_item 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 add_item 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 add_item. 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.
add_item 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.
