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.

File ships in the package but is absent from the source [пакет] chess_esca_mcp/__init__.py:1, [пакет] chess_esca_mcp/__main__.py:1, [пакет] chess_esca_mcp/facts.py:1 и ещё 3

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.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Chess Esca — questions

Answers built from our own checks of this server.

Why is there no uptime for Chess Esca?

Chess Esca 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 chess-esca-mcp.

How do I connect Chess Esca?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls chess-esca-mcp straight from pypi; nothing to host, nothing to sign up for.

Is Chess Esca open source?

Yes — it is published under the MIT licence, written in Rust and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
