Über den Server

Connects to the Etherscan V2 API for read-only onchain data. You can check native balances, list normal and internal transactions, fetch token transfers (ERC-20, ERC-721, ERC-1155), read verified contract source and ABI, search event logs, check transaction status and get gas price recommendations. A chainid parameter selects the chain.

The keyless endpoint at https://mcp-keyless.etherscan.io/mcp is hosted over Streamable HTTP and needs no sign-in or API key, with limited tools and its own rate limits. A second endpoint, https://mcp.etherscan.io/mcp, accepts your Etherscan API key in an Authorization header. The tools cannot sign or broadcast transactions or change state.

Einrichtung

Jeder Client verbindet sich mit mcp-keyless.etherscan.io. Wähl deinen; die Seite merkt sich deine Wahl.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport http etherscan https://mcp-keyless.etherscan.io/mcp
  1. Start Claude Code and type /mcp. etherscan should show as connected.

Add --scope user to make it available in every project, not just this one.

Claude Desktop

  1. Open Settings → Connectors and click Add custom connector.
  2. Name it Etherscan and paste this URL:
https://mcp-keyless.etherscan.io/mcp
  1. Click Add. Its tools appear in the chat’s tools menu.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

claude.ai

  1. Open the connector form on claude.ai. This button fills in the name and URL for you:
  1. Check that the URL reads https://mcp-keyless.etherscan.io/mcp and click Add.
  2. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

ChatGPT

  1. On chatgpt.com, open Settings → Security and login and turn on Developer mode.
  2. Go to chatgpt.com/plugins and click + to create an app for a remote MCP server.
  3. Paste https://mcp-keyless.etherscan.io/mcp as the server URL and choose No authentication.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

Cursor

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json
{
  "mcpServers": {
    "etherscan": {
      "url": "https://mcp-keyless.etherscan.io/mcp"
    }
  }
}

VS Code

Or from a terminal:

code --add-mcp '{"name":"etherscan","type":"http","url":"https://mcp-keyless.etherscan.io/mcp"}'

Or commit it to the repo in .vscode/mcp.json:

.vscode/mcp.json
{
  "servers": {
    "etherscan": {
      "type": "http",
      "url": "https://mcp-keyless.etherscan.io/mcp"
    }
  }
}

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "etherscan": {
      "serverUrl": "https://mcp-keyless.etherscan.io/mcp"
    }
  }
}
  1. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add etherscan --url https://mcp-keyless.etherscan.io/mcp

Or edit ~/.codex/config.toml directly:

config.toml
[mcp_servers.etherscan]
url = "https://mcp-keyless.etherscan.io/mcp"

Gemini CLI

gemini mcp add --transport http etherscan https://mcp-keyless.etherscan.io/mcp

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI’s settings file.

{
  "mcpServers": {
    "etherscan": {
      "type": "http",
      "url": "https://mcp-keyless.etherscan.io/mcp"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://mcp-keyless.etherscan.io/mcp.

Häufige Fragen

Can I paste mcp.tc/i/etherscan into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://mcp-keyless.etherscan.io/mcp, so your client talks to Etherscan directly. The quick link is for sharing: it opens this page, with setup steps for every client.

Does Etherscan need an API key or a sign-in?

No. Etherscan doesn’t ask for an account or key.

Is Etherscan a remote or a local server?

Remote. Etherscan hosts it at https://mcp-keyless.etherscan.io/mcp, and it speaks Streamable HTTP. There’s nothing to install.

What can Etherscan do?

It has 16 tools, including get_native_balance, get_transactions und get_internal_transactions. You can Check native coin balances for an address, List normal and internal transactions und Get ERC-20, ERC-721 and ERC-1155 token transfers.

Which clients can use it?

Any client that supports remote MCP servers: Claude Code, Claude Desktop, claude.ai, ChatGPT in developer mode, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. The setup steps cover each one.

Who wrote this page?

mcp.tc’s robot read Etherscan’s own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can’t confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
