"context_servers": {
"ledger": {
"url": "https://rackrates.dev/mcp"
}
}

02
Save the file and restart Zed.

03
Ask for something cheapest_for_spec does. Zed lists the server's tools on connect and calls cheapest_for_spec itself — you do not invoke it by name.

If nothing happens, check the server is running and that Rack Rates'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 5 November 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.
