THE RISK

Why reset_session needs a policy

The tool irreversibly resets session state (hint level and progress) back to zero, discarding any accumulated tutoring progress. This is a destructive operation because the prior session state cannot be recovered. Severity is medium since it only affects a single user's session progress rather than broader data or system state.

From the tool's definition Resets the tutoring session for a problem back to hint level 0

POLICY

How to control reset_session

PolicyLayer is an MCP gateway — it sits between your AI agents and Interactive Leetcode, and nothing reaches the server without passing your rules. This is the rule we recommend for reset_session:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "reset_session"
  ]
}

reset_session disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Interactive Leetcode — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about reset_session

What does the reset_session tool do? +

Resets the tutoring session for a problem back to hint level 0. Use when the user wants to re-attempt the problem from scratch. It is categorised as a Destructive tool in the Interactive Leetcode MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on reset_session? +

Register the Interactive Leetcode MCP server in PolicyLayer and add a rule for reset_session: 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 Interactive Leetcode. Nothing to install.

What risk level is reset_session? +

reset_session is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit reset_session? +

Yes. Add a rate_limit block to the reset_session 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.

How do I block reset_session completely? +

Set action: deny in the PolicyLayer policy for reset_session. 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.

What MCP server provides reset_session? +

reset_session is provided by the Interactive Leetcode MCP server (@sperekrestova/interactive-leetcode-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Interactive Leetcode tool call.

Start from Interactive Leetcode, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
