AI agents call list_problem_solutions 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 retrieves and queries community solutions metadata from LeetCode without creating, modifying, executing, or deleting any data. It is a straightforward read operation with minimal security risk - the worst case is information disclosure of publicly available LeetCode community content.
From the tool's definition Tool name contains 'list' and description states 'Retrieves a list...including only metadata'. The operation is read-only with no modification or execution of code.
Attacks that exploit this kind of access
Retrieves a list of community solutions for a specific LeetCode problem, including only metadata like topicId. To view the full content of a solution, use the. 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 list_problem_solutions: 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.
list_problem_solutions 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 list_problem_solutions 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 list_problem_solutions. 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.
list_problem_solutions 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.
