AI agents call redmine_get_current_user 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 read-only access to user profile information. It has no side effects, does not modify data, and poses minimal risk even if called by an AI agent. The worst outcome would be information disclosure of the authenticated user's own profile, which is already known to the API key holder.
From the tool's definition Tool retrieves user details without modifying, creating, or deleting data. Description explicitly states 'Get the details of the currently authenticated Redmine user', which is a query/retrieval operation.
Attacks that exploit this kind of access
[Stable] Get the details of the currently authenticated Redmine user (identified by REDMINE_API_KEY). 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_get_current_user: 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_get_current_user 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_get_current_user 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_get_current_user. 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_get_current_user 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.
