MCP Server Leetcode

What doggybee/mcp-server-leetcode MCP server does

The doggybee/mcp-server-leetcode MCP server connects an MCP-compatible AI assistant with LeetCode data. It covers three main areas: problems, user information, and contests. Agents can retrieve the daily challenge, request a problem by its title slug, or search problem metadata using optional tags, difficulty, pagination limit, and offset values.

User-focused operations accept a LeetCode username and can return profile information, submission history, or contest rankings. Contest lookup uses a contest slug to retrieve contest details. The available material describes access to LeetCode data; it does not list a tool for submitting solutions or executing code.

How it works

The package runs as a command-line MCP server. After installation, an MCP client starts the mcp-server-leetcode executable and communicates with it through the client configuration. The repository also exposes a programmable LeetCodeService API for JavaScript applications, including methods for fetching the daily challenge and searching problems.

In addition to callable tools, the server defines URI resources. Problem resources include leetcode://daily-challenge, individual problem paths using a title slug, and a filterable problem-list URI. User resources provide profile, submissions, and contest-ranking paths keyed by username. These resources can be useful when a client supports MCP resource browsing as well as tool invocation.

Setup and configuration

Install the npm package globally with npm install -g @mcpfun/mcp-server-leetcode, then start the server with mcp-server-leetcode. A local package installation is also documented, and the repository can be cloned and built for development with npm scripts.

For Claude Desktop, add an MCP server entry whose command is mcp-server-leetcode. The README also shows a development configuration that starts the compiled JavaScript file with Node. No environment variables, API keys, or other credentials are specified in the provided material.

The package is published as @mcpfun/mcp-server-leetcode. The repository is licensed under MIT. The documented client integration is Claude for Desktop, while the server itself follows the MCP tool and resource model.

Tools and capabilities

The doggybee/mcp-server-leetcode MCP server exposes these tools:

• get-daily-challenge retrieves the daily challenge.
• get-problem fetches details for a problem identified by titleSlug.
• search-problems filters problems by optional tags and difficulty and supports limit and skip values.
• get-user-profile retrieves information for a supplied username.
• get-user-submissions returns submission history with an optional result limit.
• get-user-contest-ranking retrieves contest rankings for a username.
• get-contest-details fetches information for a contest identified by contestSlug.

The repository describes the server as providing fast access to the LeetCode API, but it does not specify API rate limits, response schemas, or a separate authentication configuration. Check those operational details before deploying it for high-volume use.
