Etherscan MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for Etherscan MCP Server?

Etherscan MCP Server runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package etherscan-mcp-server was installed 43 times last week.

Is Etherscan MCP Server still maintained?

The author archived this repository on GitHub, meaning it is no longer maintained. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Etherscan MCP Server?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls etherscan-mcp-server straight from npm; nothing to host, nothing to sign up for.

How many people use Etherscan MCP Server?

The npm package etherscan-mcp-server was installed 43 times in the last week. Week over week that is +11%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Etherscan MCP Server open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
