Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command src/codeforces_mcp/sandbox.py:12, [пакет] src/codeforces_mcp/sandbox.py:12

        res = subprocess.run(cmd, capture_output=True, text=True, timeout=15)

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Codeforces MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Codeforces MCP?

Codeforces MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package codeforces-mcp-avinash was installed 1 346 times last week.

How do I connect Codeforces MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls codeforces-mcp-avinash straight from pypi; nothing to host, nothing to sign up for.

How many people use Codeforces MCP?

The pypi package codeforces-mcp-avinash was installed 1 346 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Codeforces MCP open source?

We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
