BNB Chain MCP Server

What it does

When your agent uses it

• Connecting an MCP client to the BNB Chain server
• Querying blocks, balances or contracts on BNB Chain or opBNB
• Sending token or NFT transfers from a configured wallet
• Registering an agent under ERC-8004 through the MCP tool

Example prompts

• “Add the bnbchain-mcp server to my Claude Desktop config in read-only mode.”
• “Read the current block number on opBNB with the MCP tools.”
• “Register my agent on-chain with register_erc8004_agent.”

Requirements

• Node.js with npx to run `@bnb-chain/mcp@latest`
• A `PRIVATE_KEY` in the server environment, only for state-changing tools
• An MCP client such as Cursor or Claude Desktop

Workflow steps

6 steps, taken from the step headings in SKILL.md.

1. 1MCP server config
2. 2Credentials and environment
3. 3Agent registration (ERC-8004)
4. 4Quick reference — tools and prompts
5. 5Reference files (per-tool usage)
6. 6Safety and best practices

What it can do on your machine

Read from SKILL.md and the folder at commit fa89195. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npx
  • bun

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • github.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • PRIVATE_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

BNB Chain MCP Server loads about 1.7k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 635 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~94

When it runs · the whole SKILL.md, loaded when a task matches

~1.7k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~4.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
