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
uxcis installed and available inPATH.- Network access to
https://mcp.etherscan.io/mcp. - An Etherscan API key is available for authenticated calls.
Core Workflow
- Confirm endpoint and protocol with help-first probing:
uxc https://mcp.etherscan.io/mcp -h- expected unauthenticated behavior today:
401 Unauthorized
- Configure credential/binding for repeatable auth:
uxc auth credential set etherscan-mcp --auth-type bearer --secret-env ETHERSCAN_API_KEY
