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#

ConstraintRequirementRPC ProviderAny Ethereum JSON-RPC endpointPrivate KeyMust have contract permissionsGas LimitAdjust based on function complexityNetworkMust match contract deployment
