What list_group_members does on Iconnect
AI agents call list_group_members to retrieve information from Iconnect without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_group_members is rated Low
This tool performs a read-only operation to retrieve contact group membership information. It queries existing data from the Apple Contacts system without creating, modifying, deleting, or executing anything. The blast radius is minimal—unauthorized access could expose contact lists, but the tool itself cannot alter, delete, or cause financial harm.
From the tool's definition Tool name 'list_group_members' and description 'List contacts in a specific group' indicate a query operation that retrieves data without modification or side effects.
Attacks that exploit this kind of access
The rule that runs list_group_members safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Iconnect, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_group_members, this is the rule to start with:
list_group_members is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Iconnect, apply this rule, and every list_group_members call is checked against it from then on.

List contacts in a specific group. It is categorised as a Read tool in the Iconnect MCP Server, which means it retrieves data without modifying state.
Register the Iconnect MCP server in PolicyLayer and add a rule for list_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 Iconnect. Nothing to install.
list_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 list_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 list_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.
list_group_members is provided by the Iconnect MCP server (iconnect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
