AI agents call redmine_list_roles 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 queries and returns role information without side effects. It is a straightforward read operation that retrieves existing data from the Redmine instance. No data is created, modified, deleted, or executed. The low severity reflects that listing roles poses minimal risk even if misused by an agent, as it only exposes informational metadata.
From the tool's definition Tool name contains 'list' and description states 'List all roles in the Redmine instance. Returns role IDs and names' — a data retrieval operation with no modification or deletion.
Attacks that exploit this kind of access
[Alpha] List all roles in the Redmine instance. Returns role IDs and names for role assignment. 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 redmine_list_roles: 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.
redmine_list_roles 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 redmine_list_roles 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 redmine_list_roles. 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.
redmine_list_roles is provided by the Redmine MCP server (jesusr00/mcp-server-redmine). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
