Balance Operations

• `get_balance(address: str) -> str`: Get BNB balance of an address
• `get_token_balance(address: str, token_address: str) -> str`: Get token balance of an address

Transfer Operations

• `transfer(recipient_address: str, amount: Decimal = 0.01) -> dict`: Transfer BNB to an address
• `transfer_token(recipient_address: str, token_address: str, amount: Decimal = 0.01) -> dict`: Transfer tokens to an address

Trading Operations

• `swap_token(token_in: str, token_out: str, amount: Decimal = 0.01) -> dict`: Swap between tokens
• `get_token_price(token_address: str) -> float`: Get token price in BNB
• `buy_token(token_address: str, amount: Decimal = 0.01) -> dict`: Buy tokens with BNB
• `sell_token(token_address: str, amount: Decimal = 0.01) -> dict`: Sell tokens for BNB

Reward Operations

• `claim_rewards(token_address: str) -> dict`: Claim rewards for a token

Running the Service

git clone https://github.com/unibaseio/beeper-mcp.git
cd beeper-mcp
# start server over stdio
uv run src/beeper_mcp/server.py

+ start using sse

The sse service will start on port 8000 by default. You can specify a different port using the `--port` argument:

uv run src/beeper_mcp/server.py --port 8008 --transport=sse

Configuration on Claude/Windsurf/Cursor/Cline

{
  "mcpServers": {
    "beeper": {
      "command": "uv",
      "args": [
        "--directory",
        "path/to/beeper-mcp",
        "run", 
        "src/beeper_mcp/server.py"
        ],
      "env": {
        "BEEPER_ACCOUNT": "your account, 0x...",
        "BEEPER_SECRET_KEY": "your private key or in .env",
        "BEEPER_TARGET_TOKEN": "default token address",
        "BEEPER_CHAIN": "chain type "
      }
    }
  }
}

Notes

• All amounts are in native units (e.g., BNB, tokens)
• Token addresses should be provided in the correct format
• Make sure you have sufficient BNB for gas fees
• The service supports both BSC mainnet and testnet
• All operations return detailed response objects with transaction hashes and status information
• The service includes built-in error handling and status tracking for transactions
