AI agents call courses to retrieve information from Moodle Connector without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves course data from the Moodle API with no side effects. It queries enrolled courses for the authenticated user, which is a simple data retrieval operation. The low severity reflects minimal blast radius: unauthorized course list disclosure affects privacy but does not enable destructive actions, financial harm, or system compromise.
From the tool's definition Tool name and description state 'Get list of enrolled courses' - a read-only operation that retrieves course information without modifying or executing actions.
Documented attack patterns abuse exactly the kind of access courses gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Moodle Connector, and nothing reaches the server without passing your rules. This is the rule we recommend for courses:
{
"version": "1",
"default": "deny",
"tools": {
"courses": {}
}
}courses is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get list of enrolled courses. It is categorised as a Read tool in the Moodle Connector MCP Server, which means it retrieves data without modifying state.
Register the Moodle Connector MCP server in PolicyLayer and add a rule for courses: 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 Moodle Connector. Nothing to install.
courses 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 courses 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 courses. 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.
courses is provided by the Moodle Connector MCP server (jabir-srj/moodle-connector). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Moodle Connector, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
