Install & config

Client config (built from the install command this repo gives)

{
  "mcpServers": {
    "xiaok-etherscan-mcp": {
      "command": "npx",
      "args": ["tsx", "/PATH/TO/YOURPROJECT/src/index.ts"]
    }
  }
}

Parsed from the README we fetched on 2026-11-06; we have not executed it.

command/args come from the install command the repository states. When it is ambiguous, the project README wins.

VS Code (.vscode/mcp.json - the key is servers)

{
  "servers": {
    "xiaok-etherscan-mcp": {
      "command": "npx",
      "args": ["tsx", "/PATH/TO/YOURPROJECT/src/index.ts"]
    }
  }
}

Same server, but VS Code keeps it under <code>servers</code>.

Claude Code (command line)

claude mcp add --transport stdio xiaok-etherscan-mcp -- npx tsx /PATH/TO/YOURPROJECT/src/index.ts

Claude Code does not read a config file; add the server with this command.
