Summary
Connects Claude to the Codeforces competitive programming platform through eight read-only API tools. You can pull user profiles and rating histories, browse recent submissions, list contests and their standings, search the problemset with optional tag filters, and view blog entries. Handles batch lookups for up to 10,000 users at once. Built on the Pipeworx gateway, so you can either connect to this standalone server or use the full gateway that includes 673+ other data sources. Useful if you're building coding interview prep tools, analyzing competitive programming trends, or just want Claude to look up contest results and problem statistics without leaving the conversation.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"codeforces": {
"url": "https://gateway.pipeworx.io/codeforces/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 673+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Codeforces data" })
The gateway picks the right tool and fills the arguments automatically.
