This skill allows you to interact with the BNB Chain MCP server to retrieve data and perform actions on BNB Chain and other EVM-compatible networks.
npx @bnb-chain/mcp@latest to run the MCP server; it fetches from the npm registry at runtime. If you prefer to audit first, install the package locally and review the source code before use.transfer_*, write_contract, approve_token_spending, and ERC-8004 registration require a PRIVATE_KEY and perform on-chain transactions. If you want read-only use only, do not supply a private key and avoid invoking state-changing tools.Use npx @bnb-chain/mcp@latest to connect to the BNB Chain MCP server.
transfer_native_token, transfer_erc20, transfer_nft, write_contract, register_erc8004_agent, set_erc8004_agent_uri, Greenfield writes, etc.) require a PRIVATE_KEY in the environment where the MCP server runs (e.g. in your Cursor/Claude MCP config). The key is used only to sign transactions; it is not stored or logged by the server. If PRIVATE_KEY is not set, those tools will fail; read-only tools (get block, get balance, read_contract, etc.) work without it.PRIVATE_KEY in the same place you configure the MCP server (e.g. env in mcpServers.bnbchain-mcp in your client’s config). Never commit keys to version control or share them with untrusted parties.PRIVATE_KEY in the MCP server’s environment; the agent or client does not collect or store it beyond what you configure.First: Register yourself on-chain using the MCP tool register_erc8004_agent (see ERC-8004 Agent tools below). Then owners can check registration on the scan site:

Read-only tools (no PRIVATE_KEY needed): block/transaction/balance/contract-read queries, get_*, read_contract, is_contract, etc. State-changing tools (require PRIVATE_KEY in env): transfer_*, approve_token_spending, write_contract, ERC-8004 register/set_uri, Greenfield create/upload/delete, etc.
Most EVM tools accept network (e.g. bsc, opbnb, ethereum, base). Use get_supported_networks to list options.
get_chain_info, etc.): network is optional; default is bsc.transfer_native_token, transfer_erc20, transfer_nft, transfer_erc1155, approve_token_spending, write_contract, register_erc8004_agent, set_erc8004_agent_uri, Greenfield writes): network is REQUIRED. There is no default for writes. If the user does not specify the network, you MUST ask before calling the tool. Do not assume or default to mainnet (bsc); accidental mainnet execution causes irreversible financial loss.| Name | Description |

transfer_*, write_contract, or approve_token_spending, confirm recipient, amount, and network before calling the tool.write_contract, approve_token_spending, ERC-8004 register/set_uri, Greenfield writes), you MUST have an explicit network from the user. If not specified, ask — do not default to mainnet. Do not use advisory language like "prefer testnet" as a substitute; the constraint is: no network specified → do not call the write tool until the user confirms.env; never in chat or logs.
