Get detailed system performance metrics
AI agents call system-metrics to retrieve information from Redmine MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and returns system performance data. It has no capability to modify, delete, execute code, or cause financial impact. The low severity reflects minimal risk from an AI misusing a metrics query—the worst outcome is information disclosure of non-sensitive operational data.
From the tool's definition Tool name 'system-metrics' and description 'Get detailed system performance metrics' indicate data retrieval with no modification or side effects. Returns metrics/monitoring data only.

Attacks that exploit this kind of access
Get detailed system performance metrics. It is categorised as a Read tool in the Redmine MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Redmine MCP Server MCP server in PolicyLayer and add a rule for system-metrics: 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 MCP Server. Nothing to install.
system-metrics 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 system-metrics 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 system-metrics. 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.
system-metrics is provided by the Redmine MCP Server MCP server (tamu960925/mcp-redmine). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
