AI agents call list_groups to retrieve information from Redmine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation that retrieves existing group data with no side effects. The admin-only restriction limits exposure but does not change the fundamental nature of the operation. Misuse would allow an attacker to enumerate groups, which has limited direct impact compared to write, execute, destructive, or financial operations.
From the tool's definition Tool is named 'list_groups' and described as 'List all groups (admin only)' — it retrieves group information without modifying or deleting data.

Attacks that exploit this kind of access
List all groups (admin only). It is categorised as a Read tool in the Redmine MCP Server, which means it retrieves data without modifying state.
Register the Redmine MCP server in PolicyLayer and add a rule for list_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 Redmine. Nothing to install.
list_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 list_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 list_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.
list_groups is provided by the Redmine MCP server (KalvadTech/redmine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
