Add Model Ruler — AI Cost Calculators to Zed

Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

"context_servers": {
"model-ruler": {
"url": "https://modelruler.dev/mcp?dist=model_everywhere_registry_native_official_registry"
}
}
}-
02
Save the file and restart Zed.

Ask for something token-counter does. Zed lists the server's tools on connect and calls token-counter itself — you do not invoke it by name.

04
If nothing happens, check the server is running and that Model Ruler — AI Cost Calculators's identifier in your config matches the one above exactly.
Merge this into your existing settings object — do not replace the file. Zed docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 6 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.
