Create a smart collection — an automated collection populated by rules (e.g. vendor, tag, product_type, price range).
AI agents use create_smart_collection to create or update resources in Mcp Ap2 — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Ap2 environment.
This tool creates new data structures (smart collections with rules) but does not irreversibly delete data, execute arbitrary code, or move money. It is a write operation that modifies the collection state reversibly—collections can be edited or removed later.
From the tool's definition Tool description states 'Create a smart collection' which is a create operation that modifies data by establishing new automated collection rules.
Documented attack patterns abuse exactly the kind of access create_smart_collection gives an agent:
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 create_smart_collection:
{
"version": "1",
"default": "deny",
"tools": {
"create_smart_collection": {
"limits": [
{
"counter": "create_smart_collection_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_smart_collection 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 smart collection — an automated collection populated by rules (e.g. vendor, tag, product_type, price range). It is categorised as a Write tool in the Mcp Ap2 MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Ap2 MCP server in PolicyLayer and add a rule for create_smart_collection: 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 Ap2. Nothing to install.
create_smart_collection 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 create_smart_collection 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 create_smart_collection. 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.
create_smart_collection is provided by the Mcp Ap2 MCP server (@codespar/mcp-ap2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Ap2, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
