      "command": "node",
      "args": [
        "/ABSOLUTE/PATH/TO/PARENT/FOLDER/mcp-server-web3/build/index.js"

}

You run an MCP (Multi-Client Protocol) server that lets an MCP client request and execute the Web3-related functions. This server is a lightweight, local bridge that runs a Node.js process to provide Web3 capabilities to clients through the MCP framework.

How to use

Start by ensuring the server is built and available as a runnable index.js file. You will run a Node.js process that loads the built code and exposes the MCP endpoints for Web3 functionality. You configure the runtime environment to include your API key for CoinMarketCap, then start the server so your MCP client can connect.

How to install

# Prerequisites
node -v
npm -v
# or if you prefer yarn, ensure yarn is available

# 1) Install dependencies
yarn

# 2) Build the server code into index.js
yarn build

# 3) Configure the MCP environment and path for your client
# Use your actual absolute path to the built index.js in the following configuration.
# Then save the config where your MCP client expects it.

Additional content

Configure the MCP server to run the built index.js with the required environment variable for API access. The server is started by invoking Node with the path to the built file and providing your API key in the environment. Below is the explicit configuration you should apply to your MCP client setup. Replace the absolute path with the real path on your machine.
