Gets all members of a group
AI agents call get_group_members to retrieve information from Smartsheet MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries group membership information without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval operation consistent with the Read category. Severity is low as group membership lists are typically non-sensitive operational metadata, and exposure would not enable direct harm without subsequent actions.
From the tool's definition Tool name 'get_group_members' and description 'Gets all members of a group' indicate retrieval of existing data with no modification or side effects.
Attacks that exploit this kind of access
Gets all members of a group. It is categorised as a Read tool in the Smartsheet MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Smartsheet MCP Server 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 Smartsheet MCP Server. 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 Smartsheet MCP Server MCP server (thomaswtwrt/smar-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
