Adds products to cart by selecting from the most recent search_products result page. No additional search is performed.
AI agents use add_items_to_cart to create or update resources in Frisco MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frisco MCP environment.
This tool creates or modifies cart data reversibly. Adding items to a cart is a Write operation—it changes state but can be undone (via remove_item_from_cart or clear_cart). While it occurs in a financial context (grocery shopping), the tool itself does not move money or commit financial obligations; checkout is separate ('checkout preparation').
From the tool's definition Tool description states it 'Adds products to cart', which is a create/modify operation on cart data. It modifies the shopping cart state by adding items to it.
Documented attack patterns abuse exactly the kind of access add_items_to_cart gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Frisco MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for add_items_to_cart:
{
"version": "1",
"default": "deny",
"tools": {
"add_items_to_cart": {
"limits": [
{
"counter": "add_items_to_cart_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_items_to_cart 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.

Adds products to cart by selecting from the most recent search_products result page. No additional search is performed. It is categorised as a Write tool in the Frisco MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Frisco MCP server in PolicyLayer and add a rule for add_items_to_cart: 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 Frisco MCP. Nothing to install.
add_items_to_cart 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_items_to_cart 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_items_to_cart. 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_items_to_cart is provided by the Frisco MCP server (mkidawa/frisco-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Frisco MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
