Gemini CLI bsc token preflight bsc_token_preflight

How to: Gemini CLI bsc token preflight bsc_token_preflight

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

Add bsc token preflight to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "bsc-token-preflight": {
      "httpUrl": "https://brainonbnb.com/mcp/preflight"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that bsc token preflight'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 11 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.
