AI agents call get_member_results to retrieve information from Groupme without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves status information about a previously-initiated add_members operation. It queries results without modifying, deleting, or executing anything. The worst-case misuse would be information disclosure about group membership operations, which is low severity.
From the tool's definition Tool name 'get_member_results' and description 'Poll the result of an add_members request' indicate a query/retrieval operation with no side effects. The verb 'poll' and 'get' are characteristic of read operations.
Attacks that exploit this kind of access
Poll the result of an add_members request. It is categorised as a Read tool in the Groupme MCP Server, which means it retrieves data without modifying state.
Register the Groupme MCP server in PolicyLayer and add a rule for get_member_results: 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 Groupme. Nothing to install.
get_member_results 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_member_results 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_member_results. 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_member_results is provided by the Groupme MCP server (kalebjs/groupme-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
