Etherscan MCP Skill

Use this skill to run Etherscan MCP operations through uxc.

Reuse the uxc skill for shared protocol discovery, output parsing, and generic auth/binding flows.

Prerequisites

  • uxc is installed and available in PATH.
  • Network access to https://mcp.etherscan.io/mcp.
  • An Etherscan API key is available for authenticated calls.

Core Workflow

  1. Confirm endpoint and protocol with help-first probing:
    • uxc https://mcp.etherscan.io/mcp -h
    • expected unauthenticated behavior today: 401 Unauthorized
  2. Configure credential/binding for repeatable auth:
    • uxc auth credential set etherscan-mcp --auth-type bearer --secret-env ETHERSCAN_API_KEY
