Check orchard-mcp permissions status, list accessible Calendar accounts, Mail accounts, and Reminders status. Run this first to diagnose access issues.
AI agents call system.doctor to retrieve information from Orchard without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and reports on permission statuses and lists accessible accounts/services. It performs no writes, executions, or destructive actions. It is a diagnostic/read-only tool.
From the tool's definition 'Check orchard-mcp permissions status, list accessible Calendar accounts, Mail accounts, and Reminders status' and 'Run this first to diagnose access issues'
Documented attack patterns abuse exactly the kind of access system.doctor gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Orchard, and nothing reaches the server without passing your rules. This is the rule we recommend for system.doctor:
{
"version": "1",
"default": "deny",
"tools": {
"system.doctor": {}
}
}system.doctor is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check orchard-mcp permissions status, list accessible Calendar accounts, Mail accounts, and Reminders status. Run this first to diagnose access issues. It is categorised as a Read tool in the Orchard MCP Server, which means it retrieves data without modifying state.
Register the Orchard MCP server in PolicyLayer and add a rule for system.doctor: 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 Orchard. Nothing to install.
system.doctor 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.doctor 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.doctor. 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.doctor is provided by the Orchard MCP server (l22-io/orchard-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Orchard, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
