AI agents call cursor_list_members to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves/queries data about team members with no side effects, modifications, or external operations triggered. It falls squarely into the Read category. Severity is low because exposing team member lists, while potentially sensitive, is a common organizational query with limited blast radius in typical misuse scenarios.
From the tool's definition Tool name is 'cursor_list_members' and description states 'List all members of the Cursor team' — a query operation that retrieves team membership information without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access cursor_list_members gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for cursor_list_members:
{
"version": "1",
"default": "deny",
"tools": {
"cursor_list_members": {}
}
}cursor_list_members is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all members of the Cursor team. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for cursor_list_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 Sage MCP. Nothing to install.
cursor_list_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 cursor_list_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 cursor_list_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.
cursor_list_members is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
