Codeforces MCP server for AI agents

This MCP server provides seamless access to the Codeforces API through a standardized Model Context Protocol interface. It allows you to interact with Codeforces contests, user data, submissions, and ratings in a structured way.

Installation

Using Docker (Recommended)

The simplest way to get started with the Codeforces MCP server is using Docker:

Pull the image from Docker Hub:

docker pull mohamed2x/codeforces-mcp

Run the container:

docker run -i --rm mohamed2x/codeforces-mcp:latest

Available Tools

The server provides various tools organized into categories for accessing Codeforces data.

Contest Tools

These tools help you interact with Codeforces contests:

get_contest_list - Retrieve a list of contests with optional filtering
get_contest_rating_changes - Access rating changes after a specific contest
get_contest_standings - Get contest standings with customization options
get_contest_status - View submissions for a specific contest

General Tools

Additional utilities for platform-wide data:

get_recent_submissions - Access recent submissions across the platform

Configuration

The server connects to the official Codeforces API at https://codeforces.com/api and runs on stdio transport by default. No additional configuration is required after installation.

System Requirements

The server has minimal dependencies:

fastmcp - The MCP server framework
httpx - An asynchronous HTTP client
urllib.parse - For URL parameter encoding

These dependencies are included in the Docker image, so you don't need to install them separately when using the recommended Docker installation method.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "codeforces-mcp" '{"command":"docker","args":["run","-i","--rm","mohamed2x/codeforces-mcp:latest"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "codeforces-mcp": {
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "mohamed2x/codeforces-mcp:latest"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "codeforces-mcp": {
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "mohamed2x/codeforces-mcp:latest"
            ]
        }
    }
}
