Add via CLI

Basic endpoint (recommended start)

gemini mcp add --transport http boar-blockchain-mcp-basic https://mcp.boar.network/basic

Advanced endpoint

gemini mcp add --transport http boar-blockchain-mcp-advanced https://mcp.boar.network/advanced

Or add via config file

Edit ~/.gemini/settings.json (create it if it doesn't exist):

{
  "mcpServers": {
    "boar-blockchain-mcp-basic": {
      "httpUrl": "https://mcp.boar.network/basic"
    },
    "boar-blockchain-mcp-advanced": {
      "httpUrl": "https://mcp.boar.network/advanced"
    }
  }
}

Verify

Start the Gemini CLI: gemini
Ask: "What is the ETH balance of vitalik.eth?"
Gemini should discover and call the eth_get_balance tool.

Troubleshooting

"Unknown transport type" error — Update Gemini CLI to the latest version.
Tools not discovered — Run gemini mcp list to check if the servers are registered. Re-add if needed.
Connection errors — Verify that https://mcp.boar.network/basic is reachable from your network.
