Safety Assessment

This server is generally safe for read-only operations. Accessing and modifying user notes requires authentication, which introduces a moderate risk if the session cookie is compromised. Ensure proper handling and storage of the session cookie to mitigate potential risks.

Primarily read-only access to problem and user data.
Authentication required for accessing private user data and notes.
No direct code execution or system-level access.
MCP framework provides a layer of abstraction and control.

Authenticated access allows modification of user notes.
Potential for information leakage if session cookie is compromised.
Rate limiting not explicitly mentioned, potential for abuse.
Reliance on LeetCode's API security.
