AI agents call get_user_profile 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 only retrieves and returns profile data (user stats, solved problems, profile details) from LeetCode. There is no indication of data modification, deletion, code execution, or financial impact. The action is purely informational retrieval, consistent with Read category tools like 'get', 'fetch', or 'query' operations.
From the tool's definition Tool name 'get_user_profile' and description 'Retrieves profile information about a LeetCode user' indicate a read-only operation that queries existing data without modification or side effects.
Attacks that exploit this kind of access
Retrieves profile information about a LeetCode user, including user stats, solved problems, and profile details. 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_user_profile: 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_user_profile 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_user_profile 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_user_profile. 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_user_profile 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.
