Overview

AI-generated overview

A hosted MCP server exposing 71 Etherscan tools so an assistant can query blockchain data, metrics and on-chain analytics without an API key.

What you can do
Query Etherscan blockchain data and on-chain records through tools mapped one-to-one to real API endpoints, covering accounts, transactions, blocks and contracts, plus metrics and on-chain analytics. Each tool corresponds to a documented Etherscan endpoint rather than an invented one.
When to use it
Use it when an assistant needs to look up Ethereum on-chain data, such as addresses, transactions or contract information, and you want a hosted endpoint with no key setup.
Requirements
A remote Streamable HTTP endpoint; no local runtime, account, API key or authentication is required according to the README.
Before you install
The server is third-party hosted and free with no auth, so queries pass through an external service; treat returned on-chain data as informational and verify anything used for financial decisions.

Installation

In SourceWeft

  1. Open Etherscan Api Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.junct-bot%2Fetherscan-api-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
