• 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

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

• 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
