@bnb-chain
Basic information
A MCP server for BNB Chain that supports BSC, opBNB, Greenfield, and other popular EVM-compatible networks.
Add this server to your MCP-compatible client using the configuration below.
{
"mcpServers": {
"bnbchain-mcp": {
"command": "npx",
"args": [
"-y",
"@bnb-chain/mcp@latest"
],
"env": {
"PRIVATE_KEY": "your_private_key_here. (optional)",
"BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION": "false"
}
}
}
}Register an agent on the ERC-8004 Identity Registry. Mints an on-chain agent identity (NFT) and returns the agent ID. Use BSC or BSC Testnet; the agentURI should point to a JSON metadata file (AgentURI format) with name, description, image, and services (e.g. MCP endpoint).
Update the metadata URI for an existing ERC-8004 agent. Caller must be the owner of the agent NFT.
Get agent info from the ERC-8004 Identity Registry: owner address and tokenURI (metadata URI).
Get the verified payment wallet address for an ERC-8004 agent (for x402 / agent payments). Set on-chain via setAgentWallet; defaults to owner on registration.
Get block metadata by hash. Returns number, hash, timestamp, gasUsed, transaction count, and optionally transaction hashes (not full tx data).
Get block metadata by number. Returns number, hash, timestamp, gasUsed, transaction count, and optionally transaction hashes (not full tx data).
Get the latest block metadata. Returns number, hash, timestamp, gasUsed, transaction count, and optionally transaction hashes (not full tx data).
Check if an address is a smart contract or an externally owned account (EOA)
Read data from a smart contract by calling a view/pure function. Response is truncated if it exceeds maxResponseSize bytes.
Write data to a smart contract by calling a state-changing function. By default returns a preview and confirmToken—call confirm_transfer with the token to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Get chain information for a specific network
Get list of supported networks
Get ERC20 token information
Get native token balance for an address
Get ERC20 token balance for an address
Create a new ERC20 token
Get detailed information about a specific transaction by its hash. Includes sender, recipient, value, data, and more.
Estimate the gas cost for a transaction
Get the EVM address derived from a private key
Transfer native tokens (BNB, ETH, MATIC, etc.) to an address. By default returns a preview and confirmToken—call confirm_transfer with the token to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Approve another address (e.g. a DeFi protocol or exchange) to spend your ERC20 tokens. Use the exact amount needed. WARNING: Large or unlimited approvals increase risk. By default returns a preview—call confirm_transfer to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Transfer ERC20 tokens to an address. By default returns a preview and confirmToken—call confirm_transfer to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Get detailed information about a specific NFT (ERC721 token), including collection name, symbol, token URI, and current owner if available.
Get the metadata for an ERC1155 token (multi-token standard used for both fungible and non-fungible tokens). The metadata typically points to JSON metadata about the token.
Transfer an NFT to an address. By default returns a preview and confirmToken—call confirm_transfer to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Transfer ERC1155 tokens to another address. By default returns a preview and confirmToken—call confirm_transfer to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Get the balance for an account
Get a list of all storage providers in the Greenfield network
Create a new bucket in Greenfield storage
Upload a file to a Greenfield bucket
Create a folder in a Greenfield bucket
List buckets owned by the account with pagination. Returns totalCount and hasMore for paging.
List objects in a bucket with pagination. Returns totalCount and hasMore for paging.
Delete an object from a bucket
Delete a bucket
Get detailed information about a bucket
Get bucket basic information and quota usage
Get detailed information about an object in a bucket
Download an object from a bucket
Get the payment accounts for a given address
Create a new payment account. By default returns a preview and confirmToken—call confirm_transfer to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Deposit funds into a payment account. By default returns a preview and confirmToken—call confirm_transfer to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Withdraw funds from a payment account. By default returns a preview and confirmToken—call confirm_transfer to execute. Set skipConfirmation=true or BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true to execute immediately.
Get the info for a payment account
Execute a pending transfer or payment that was returned as a preview. Pass the confirmToken from the preview response and your privateKey. The token expires after 5 minutes.
BNBChain MCP is a Model Context Protocol (MCP) server that enables AI-powered interaction with BNB Chain and other EVM-compatible networks. It provides tools and resources for blockchain development, smart contract interaction, and network management through natural language.
Install and configure with your MCP client (Cursor, Claude Desktop) by adding a JSON entry that runs npx -y @bnb-chain/mcp@latest with optional environment variables PRIVATE_KEY and BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION. For local development, clone the repo, install dependencies with bun install, and run bun dev:sse.
Open Claude Desktop Settings, go to Developer, click “Edit Config”, and add the JSON configuration with `command: "npx"` and `args: ["-y", "@bnb-chain/mcp@latest"]`. Optionally set `PRIVATE_KEY` and `BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION` in the `env` object.
By default, calling a transfer or payment tool returns a preview with a short-lived `confirmToken`. No transaction is sent until you call `confirm_transfer` with that token and your private key. You can skip confirmation per call with `skipConfirmation: true` or server‑wide by setting `BNBCHAIN_MCP_SKIP_TRANSFER_CONFIRMATION=true`.
No. The SSE endpoint has no built‑in authentication, so anyone who can reach it can use the server. If public deployment is required, add an authentication layer (API keys, JWT, reverse proxy) or deploy a keyless version with only read‑only tools.
You need Node.js v17 or higher and [bun](http://bun.sh/) v1.2.10 or higher for local development. The server itself runs on any platform where Node.js is available.
Yes. The repository contains an `examples` directory that demonstrates how to set up an MCP client, authenticate, make API calls, and handle responses. You can integrate it into any custom client that supports the Model Context Protocol.
