Get the groups, companies, helpdesks and locations for the given users.
AI agents call get_user_groups to retrieve information from InvGate Service Desk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves organizational metadata (groups, companies, helpdesks, locations) associated with users. It performs a read-only query operation with no capability to modify, delete, or execute external actions. The blast radius of misuse is low — an attacker could enumerate user organizational structure but cannot escalate privileges, modify data, or trigger destructive actions.
From the tool's definition Tool name is 'get_user_groups' and description states 'Get the groups, companies, helpdesks and locations for the given users' — uses the verb 'Get' which indicates retrieval/query of existing data with no modification or side effects.
Attacks that exploit this kind of access
Get the groups, companies, helpdesks and locations for the given users. It is categorised as a Read tool in the InvGate Service Desk MCP Server, which means it retrieves data without modifying state.
Register the InvGate Service Desk MCP server in PolicyLayer and add a rule for get_user_groups: 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 InvGate Service Desk. Nothing to install.
get_user_groups 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_user_groups 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_user_groups. 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_user_groups is provided by the InvGate Service Desk MCP server (oci:ghcr.io/tracegazer/invgate-service-desk-mcp:0.2.0). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
