AI agents call get_pack_items to retrieve information from Portals without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
packId | string | Yes | The id of the marketplace pack. |
Parameters from the server's own tool schema.
This tool performs a read-only query operation that retrieves and displays information about items within a marketplace pack. There is no creation, modification, deletion, code execution, or financial transaction involved. The action is purely informational, making it a Read category tool with low severity since misuse would only expose marketplace item data without operational impact.
From the tool's definition Tool description states it 'List the items contained in a marketplace pack' and 'Returns the packed children with their ids, titles, thumbnails, and metadata.' The verb 'List' and 'Returns' indicate data retrieval with no modification or side effects.

get_pack_items accepts 1 parameter: packId. Required: packId. The full parameter table on this page comes from the server's own tool schema.
Register the Portals MCP server in PolicyLayer and add a rule for get_pack_items: 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 Portals. Nothing to install.
get_pack_items is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_pack_items 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 get_pack_items. 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.
get_pack_items is provided by the Portals MCP server (portals-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
