# @xiaok/etherscan-mcp

A dynamic MCP server for interacting with Etherscan's API and services.


  


## Running Your Server

### Test with `mcp-cli`

The fastest way to test and debug your server is with `fastmcp dev`:

```bash
npx fastmcp dev server.js
npx fastmcp dev server.ts
```

This will run your server with [`mcp-cli`](https://github.com/wong2/mcp-cli) for testing and debugging your MCP server in the terminal.

### Inspect with `MCP Inspector`

Another way is to use the official [`MCP Inspector`](https://modelcontextprotocol.io/docs/tools/inspector) to inspect your server with a Web UI:

```bash
npx fastmcp inspect server.ts
```
