Frequently Asked Questions

What is Leetcode MCP Server?

Is Leetcode MCP Server safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Leetcode MCP Server and run five keyword searches over its source: auth identifiers, CORS configuration, rate-limit identifiers, the dependency manifest against a hardcoded list of 18 known-vulnerable packages, and unguarded eval/exec calls. None of them matched. A text search cannot follow a variable, judge intent, or tell you what a server does once it is running, so "nothing matched" is not "safe". What the scan does and does not cover is written out at /mcp/security.

What are alternatives to Leetcode MCP Server?

Similar MCP servers include Serena, MCP Run Python, DesktopCommanderMCP. Each serves a similar purpose but may differ in features, language, and compatibility.
