The LeetCode MCP server provides access to LeetCode problems, user data, solutions, and notes, enabling automation and intelligent interaction with the platform.
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.
Performance depends on the LeetCode API response times and network latency. Consider caching frequently accessed data to improve performance.
Cost depends on the frequency of API calls to LeetCode. Be mindful of rate limits and potential charges for excessive usage.

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.
Autonomy is limited by the need for authentication to access private data and the read-only nature of most tools. The ability to create and update notes introduces a small degree of write access.
Production Tip
Monitor LeetCode API usage to avoid rate limiting and ensure stable performance.
The session cookie is used for authentication, allowing access to private user data and the ability to create and modify notes.
You can typically find your session cookie in your browser's developer tools after logging in to LeetCode.
A compromised session cookie could allow unauthorized access to your LeetCode account, including your notes and submission history. Revoke the cookie immediately.
The documentation does not explicitly mention rate limits, but it's best practice to implement rate limiting in your application to avoid overloading the API.
No, this server primarily provides read access to LeetCode data. It does not support code submission.
Yes, the server supports both leetcode.com (Global) and leetcode.cn (China) platforms. Use the `--site` parameter to specify the desired platform.
`get_recent_submissions` retrieves all recent submissions, while `get_recent_ac_submissions` only retrieves accepted submissions.
