Gemini CLI Wicked MCP chain_nonce

How to: Gemini CLI Wicked MCP chain_nonce

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

Add Wicked MCP to Gemini CLI

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

{
  "mcpServers": {
    "wicked-mcp": {
      "httpUrl": "https://mcp.wickedapi.com/mcp"
    }
  }
}

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

Wicked MCP will not start until these are set, so chain_nonce never becomes available.

WICKEDAPI_API_KEY
WICKEDAPI_PAYER_PRIVATE_KEY

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.
