`mcp_bankless_get_abi` tool failing with deprecated V1 endpoint error

[actus-wirtenberger]

Issue Description

The mcp_bankless_get_abi tool is currently failing when attempting to fetch contract ABIs from Ethereum mainnet.

Steps to Reproduce

1. Call mcp_bankless_get_abi with the following parameters:
   • network: ethereum
   • contract: 0xE592427A0AEce92De3Edee1F18E0157C05861564

Expected Behavior

The tool should return the ABI for the specified contract.

Actual Behavior

The tool returns an error response:

{
  "status": "0",
  "message": "NOTOK",
  "result": "You are using a deprecated V1 endpoint, switch to Etherscan API V2 using https://docs.etherscan.io/v2-migration",
  "isSuccess": false
}

Root Cause

The tool appears to be using Etherscan's deprecated V1 API endpoint. Etherscan is requiring migration to their V2 API.

Suggested Fix

Update the mcp_bankless_get_abi implementation to use Etherscan API V2 endpoints as documented at: https://docs.etherscan.io/v2-migration
