Add to Claude Desktop

Edit your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "basic-crypto": {
      "command": "node",
      "args": ["/path/to/basic-mcp-server/dist/index.js"]
    }
  }
}

Usage

Once configured, ask Claude:

• "What's the current price of Bitcoin?"
• "Show me trending cryptocurrencies"
• "Give me a market overview"

Extending

To add more tools, add them to the tools object in src/index.ts:

const tools = {
  // ... existing tools
  
  my_new_tool: {
    description: "Does something useful",
    inputSchema: {
      type: "object",
      properties: {
        param1: { type: "string", description: "Parameter description" },
      },
      required: ["param1"],
    },
    handler: async (params: { param1: string }) => {
      return {
        content: [{ type: "text", text: "Result" }],
      };
    },
  },
};
