What is the Blockchain MCP MCP server?

If you want an AI assistant working directly with Blockchain MCP, the blockchain mcp mcp server is the bridge. Blockchain MCP Server with Ethereum vanity address generation, 4byte lookup, ABI encoding, and multi-chain RPC calls.

What Blockchain MCP does

A Model Context Protocol (MCP) based blockchain tools server providing Ethereum vanity address generation and Cast command functionality.

Tools it exposes

Once connected, the assistant can call these 2 tools directly:

  • Mainnet — The Mainnet tool exposed by this server
  • Testnet — All networks use public RPC endpoints to ensure stability and accessibility

Installing the blockchain mcp mcp server

The server is distributed via npm as blockchain-mcp-server, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Blockchain MCP sits in that group, and the shape of its toolset — Mainnet, Testnet — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by lienhage, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the blockchain mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

How to install the Blockchain MCP MCP server

{
  "mcpServers": {
    "blockchain": {
      "command": "npx",
      "args": ["blockchain-mcp-server"]

Configuration as documented by the project. Restart the client after saving.

Example prompts to try

  • “Use Blockchain MCP to Mainnet.”
  • “Use Blockchain MCP to Testnet.”

Frequently asked questions

It connects Blockchain MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 2 tools (Mainnet, Testnet) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Blockchain MCP directly.
