Get members of a WhatsApp group with real phone numbers. Args: group_jid (from list_all_groups), instance_name. Returns: members with roles, LID, and real phone numbers.
AI agents call get_group_members to retrieve information from Automagik Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and returns group membership data. While it exposes personal information (phone numbers), the tool itself performs no writes, deletes, executions, or financial operations. The risk is classified as low because it is a passive data retrieval with no side effects, though organizations should still control access to prevent unauthorized information disclosure.
From the tool's definition Tool retrieves WhatsApp group member information (roles, LID, phone numbers) with no modification capability. Description uses 'Get' and 'Returns' indicating data retrieval only.
Documented attack patterns abuse exactly the kind of access get_group_members gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Automagik Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for get_group_members:
{
"version": "1",
"default": "deny",
"tools": {
"get_group_members": {}
}
}get_group_members is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get members of a WhatsApp group with real phone numbers. Args: group_jid (from list_all_groups), instance_name. Returns: members with roles, LID, and real phone numbers. It is categorised as a Read tool in the Automagik Tools MCP Server, which means it retrieves data without modifying state.
Register the Automagik Tools MCP server in PolicyLayer and add a rule for get_group_members: 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 Automagik Tools. Nothing to install.
get_group_members 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_group_members 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_group_members. 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_group_members is provided by the Automagik Tools MCP server (namastexlabs/automagik-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Automagik Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
