What mcp_system_diagnostics does on Ae
AI agents call mcp_system_diagnostics to retrieve information from Ae without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why mcp_system_diagnostics is rated Low
This tool performs information retrieval only. It queries system state and performance metrics but does not create, modify, delete, or execute operations. The verb 'Get' and the nature of diagnostics as observational data collection place it clearly in the Read category with low severity since no side effects or state changes occur.
From the tool's definition Tool name 'mcp_system_diagnostics' and description 'Get detailed system diagnostics and performance information' indicate a read-only operation that retrieves diagnostic data without modifying or executing actions.
Attacks that exploit this kind of access
The rule that runs mcp_system_diagnostics safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ae, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mcp_system_diagnostics, this is the rule to start with:
mcp_system_diagnostics is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ae, apply this rule, and every mcp_system_diagnostics call is checked against it from then on.
Questions about mcp_system_diagnostics
Get detailed system diagnostics and performance information. It is categorised as a Read tool in the Ae MCP Server, which means it retrieves data without modifying state.
Register the Ae MCP server in PolicyLayer and add a rule for mcp_system_diagnostics: 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 Ae. Nothing to install.
mcp_system_diagnostics 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 mcp_system_diagnostics 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 mcp_system_diagnostics. 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.
mcp_system_diagnostics is provided by the Ae MCP server (ae-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
