I want to check the native token balance for address 0x1234567890123456789012345678901234567890 on the default BNB network using an MCP tool call. What tool and default parameter value should be used?
| Checked | Without skill | With skill |
|---|---|---|
| Names `get_native_balance` as the tool for querying account balance. | Passed | Passed |

How to connect to the BNB Chain MCP server and use its tools: blocks, transactions, contracts, tokens, NFTs, wallet, ERC-8004 agents, and Greenfield. Use this skill when working with BNB Chain / opBNB / EVM or Greenfield via MCP.
npx @bnb-chain/mcp@latest (fetches from npm at runtime). Source: github.com/bnb-chain/bnbchain-mcp.env for state-changing tools (transfers, write_contract, approve_token_spending, ERC-8004 register/set_uri, Greenfield writes). Never log or expose private keys.PRIVATE_KEY in the server environment.Add the bnbchain-mcp server to the MCP client config (e.g. Cursor MCP settings, Claude Desktop claude_desktop_config.json).
Default (stdio):
{
"mcpServers": {
"bnbchain-mcp": {
"command": "npx",
"args": ["-y", "@bnb-chain/mcp@latest"],
"env": {
"PRIVATE_KEY": ""
}
}
}
}
SSE mode: "args": ["-y", "@bnb-chain/mcp@latest", "--sse"] (and client SSE URL if required). Local dev server (e.g. bun dev:sse in bnbchain-mcp): "url": "http://localhost:3001/sse" with the same env.
Restart or reload the MCP client after changing config so the server starts.
