Gemini CLI Crypto Market Data sentiment

How to: Gemini CLI Crypto Market Data sentiment

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

Add Crypto Market Data to Gemini CLI

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

{
  "mcpServers": {
    "crypto-market-data": {
      "httpUrl": "https://crypto-market-data.zafermemon87.workers.dev/mcp"
    }
  }
}

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

Crypto Market Data will not start until these are set, so sentiment never becomes available.

X402_PRIVATE_KEY
X402_MAX_PER_CALL_USD
X402_MAX_TOTAL_USD

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 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.
