AI agents call authstatus to retrieve information from eClass MCP Server 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 returns the current authentication status. It does not modify any data, execute commands, or perform any destructive or financial operations. Misuse has minimal blast radius as it only exposes whether a session is active.
From the tool's definition 'Check authentication status with eClass' — purely retrieves current auth state, no side effects
Documented attack patterns abuse exactly the kind of access authstatus gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and eClass MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for authstatus:
{
"version": "1",
"default": "deny",
"tools": {
"authstatus": {}
}
}authstatus is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check authentication status with eClass. It is categorised as a Read tool in the eClass MCP Server MCP Server, which means it retrieves data without modifying state.
Register the eClass MCP Server MCP server in PolicyLayer and add a rule for authstatus: 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 eClass MCP Server. Nothing to install.
authstatus 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 authstatus 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 authstatus. 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.
authstatus is provided by the eClass MCP Server MCP server (sdi2200262/eclass-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from eClass MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
