Gemini CLI slicktext slicktext_get_credit_usage

How to: Gemini CLI slicktext slicktext_get_credit_usage

client:Gemini CLI transport:streamable-http tool:slicktext_get_credit_usage

Add slicktext to Gemini CLI

01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "slicktext": {
      "httpUrl": "https://slicktext.usefulapi.io/mcp"
    }
  }
}

02
Save the file and restart Gemini CLI.
03
Ask for something slicktext_get_credit_usage does. Gemini CLI lists the server's tools on connect and calls slicktext_get_credit_usage itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that slicktext'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

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 8 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.
