Chessigma MCP server
Featured official server
7 tools · Last check that passed 4 Nov 2026, 12:15 UTC
Chessigma's own remote MCP server gives an agent chess tools: opening guides and names, facts about a position or a game, links to move-by-move reviews of public Chess.com and Lichess games, the daily puzzle and Elo estimates, with no sign-in. Once a day, Stackduke connects to it the way any MCP client would, with no account and no sign-in, and lists its tools. It never runs them.

The tools the server listed at the last check that passed, at its default address and settings, with no sign-in; an account that signs in, or other settings, may see other tools. What a tool is counted as doing is Stackduke's cautious reading of the server's labels, the tool's name and its description: where they disagree it takes whichever says the tool can do most, so it overcounts on purpose. It does not say the server is safe, and it does not list what a tool cannot do. Descriptions are not shown, because they are written for models and may try to steer them.

One email when Chessigma's official MCP server adds, removes or changes tools, with what changed. Nothing else.
What to watch for
- Chessigma says it logs each request's time, method, path, IP address and user agent to limit request rates, and that its links carry utm markers to count visits from each assistant. Chessigma's MCP documentation
- For a public Chess.com or Lichess game, review_online_game answers with a chessigma.com address, and opening it loads that game into Chessigma. Chessigma's MCP documentation
How to limit it
With Chessigma's own settings, as its documentation describes them. Stackduke has not tested them.
- Chessigma says there is no account to connect and nothing to sign in to, so we recommend connecting it with no credentials. Chessigma's MCP documentation
What Stackduke is designed to do
Stackduke is designed to sit between your agents and their MCP servers: to check each tool call against your rules before it runs, hold the risky ones for a person to approve, and keep a record of what was decided.
It does not yet forward or block tool calls for customers. Today it reads what this server offers and publishes what changes.
