• Swap tokens in Pancakeswap

• Get token prices

• Buy and sell tokens

• Claim rewards of beeper tokens

• Manage default wallet and token addresses

Prerequisites

• Python >=3.10

• Access to BSC network (mainnet or testnet)

• Wallet account and private key

Environment Variables

Create a .env file in the project root with the following variables:

BEEPER_CHAIN=<bsc or bsc-testnet>
BEEPER_ACCOUNT=<your-wallet-address>
BEEPER_SECRET_KEY=<your-private-key>
BEEPER_TARGET_TOKEN=<default-token-address>  # Optional

API Endpoints

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

        "BEEPER_CHAIN": "chain type <bsc/bsc-testnet>"
      }
    }
  }
}

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
