Configuration

{
  "mcpServers": {
    "bichev-coinbase-chat-mcp": {
      "command": "node",
      "args": [
        "/path/to/coinbase-chat-mcp/mcp-server/dist/index.js"
      ],
      "env": {
        "LOG_LEVEL": "info",

You can run a secure MCP server that exposes real-time Coinbase data and a simulated wallet for learning. This server integrates with AI agents and clients via the Model Context Protocol, giving you access to live prices, market stats, historical data, and a playful circular economy that includes a beer inventory simulated in the system.

How to use

Interact with the CoinBase MCP Server through an MCP client to query prices, fetch market data, search assets, and run simulated wallet transactions. Use the built-in chat interface for natural language questions, or call the API explorer to test individual endpoints. When you want to run the server locally, point your MCP client at the local server and activate the 13 available tools, including real-time prices and the beer transaction workflow.

Additional notes

Open the MCP client you are using (Cursor IDE or Claude Desktop) and ensure the MCP endpoint coinbase_mcp is configured. The server provides 13 tools, including market data and simulated wallet functionality, and is designed to be fast and secure with rate limiting and caching. If you want to test the integration quickly, you can run the provided commands and then ask simple questions like the current Bitcoin price, or try a simulated beer purchase flow to see the complete USD → Crypto → Beer sequence in action.
