Gemini CLI FIDE Laws of Chess law_publish_answer
How to: Gemini CLI FIDE Laws of Chess law_publish_answer
Add FIDE Laws of Chess to Gemini CLI
-
01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"fide-chess": {
"httpUrl": "https://mcp.arxo.io/mcp/fide-chess"
}
}
}-
02
Save the file and restart Gemini CLI.
-
03
Ask for something law_publish_answer does. Gemini CLI lists the server's tools on connect and calls law_publish_answer itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that FIDE Laws of Chess's identifier in your config matches the one above exactly.
Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs
Set these first
FIDE Laws of Chess will not start until these are set, so law_publish_answer never becomes available.

FIDE_CHESS_MCP_CALL_TIMEOUT
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 14 October 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
