AI agents call get_problem_progress to retrieve information from Leetcode without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to fetch user progress information. It retrieves or queries data without creating, modifying, deleting, or executing any operations. The verb 'retrieves' and the absence of any state-changing operations place it squarely in the Read category. Severity is low because access to a user's problem progress is low-risk and contains no destructive or financial impact.
From the tool's definition Tool name 'get_problem_progress' and description 'Retrieves the current user' indicate a data retrieval operation with no modification, deletion, or side effects.
Attacks that exploit this kind of access
Retrieves the current user. It is categorised as a Read tool in the Leetcode MCP Server, which means it retrieves data without modifying state.
Register the Leetcode MCP server in PolicyLayer and add a rule for get_problem_progress: 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 Leetcode. Nothing to install.
get_problem_progress 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_problem_progress 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_problem_progress. 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_problem_progress is provided by the Leetcode MCP server (@jinzcdev/leetcode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
