Get an overall registry health assessment
AI agents call get_registry_health to retrieve information from Windows Diagnostics MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and analyzes registry health information without modifying any registry data or executing commands. This is consistent with other diagnostic tools on the server like 'get_system_diagnostics' and 'get_system_uptime', which are read-only operations. The blast radius is minimal—at worst, an agent misuses the output for decision-making, but the tool itself produces no side effects.
From the tool's definition Tool name and description indicate it performs assessment/analysis of registry health status, a diagnostic read operation with no modification or execution implied. No keywords like 'modify', 'delete', 'execute', or 'change' are present.
Attacks that exploit this kind of access
Get an overall registry health assessment. It is categorised as a Read tool in the Windows Diagnostics MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Windows Diagnostics MCP Server MCP server in PolicyLayer and add a rule for get_registry_health: 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 Windows Diagnostics MCP Server. Nothing to install.
get_registry_health 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 get_registry_health 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 get_registry_health. 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.
get_registry_health is provided by the Windows Diagnostics MCP Server MCP server (jackalterman/windows-diagnostic-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
