Retrieve a paginated list of all team members in the SparrowDesk account
AI agents call list_members to retrieve information from SparrowDesk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves team member information without creating, modifying, or deleting data. The verb 'Retrieve' and 'list' are characteristic of Read category tools. The severity is low because exposing a team member roster, while potentially sensitive, has limited direct impact compared to tools that modify or destroy data.
From the tool's definition Tool name 'list_members' and description 'Retrieve a paginated list of all team members' indicate a read-only query operation with no side effects.
Attacks that exploit this kind of access
Retrieve a paginated list of all team members in the SparrowDesk account. It is categorised as a Read tool in the SparrowDesk MCP Server, which means it retrieves data without modifying state.
Register the SparrowDesk MCP server in PolicyLayer and add a rule for 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 SparrowDesk. Nothing to install.
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 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 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.
list_members is provided by the SparrowDesk MCP server (sparrowdesk/sparrowdesk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
