WHAT IT DOES

What get_pack does on A3plus

AI agents call get_pack to retrieve information from A3plus without modifying anything. It is 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 pack id from create_pack or list_packs.

Parameters from the server's own tool schema.

RISK

Why get_pack is rated Low

Even though get_pack only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_pack safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A3plus, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_pack, this is the rule to start with:

get_pack Allowed

get_pack is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_pack": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect A3plus, apply this rule, and every get_pack call is checked against it from then on.

Fetch one design pack by id and its previewUrl. For a pack YOU own, the response also includes template: { home, css, tokens } — the editable source.

How do I enforce a policy on get_pack? +

Can I rate-limit get_pack? +

How do I block get_pack completely? +
