ABI-to-MCP: The Web3 Skill Architect

Workflow

1. Setup: Configure environment variables RPC_URL, PRIVATE_KEY, CONTRACT_ADDRESS
2. Read: Use read functions (view/pure) to query contract state
3. Write: Use write functions to modify contract state (requires gas)

Constraints

Read Functions

name

name()

Returns: string

Example:

const result = await name({  });

symbol

symbol()

Returns: string

Example:

const result = await symbol({  });

decimals

decimals()

Returns: uint8

Example:

const result = await decimals({  });

totalSupply

totalSupply()

Returns: uint256

Example:

const result = await totalSupply({  });

balanceOf

balanceOf(address account)

Returns: uint256

Parameters:

| account | address |

Example:

const result = await balanceOf({ account: "0x... });

allowance

allowance(address owner, address spender)

Returns: uint256

Parameters:

| owner | address | | spender | address |

Example:

const result = await allowance({ owner: "0x..., spender: "0x... });

Write Functions

transfer

Parameters:

| from | address | | to | address | | amount | uint256 |

Example:

const tx = await transferFrom({ from: value, to: value, amount: value });

mint

mint(address to, uint256 amount)

Mutability: nonpayable

Parameters:

| to | address | | amount | uint256 |

Example:

const tx = await mint({ to: value, amount: value });

burn

burn(uint256 amount)

Mutability: nonpayable

Parameters:
