MCP Server Demo (using Activity API)

An MCP server that wraps around an "Activity API" service that provides blockchain activity and holder information for SBC (Stablecoin).

Installation

npm install

Configuration

Create a .env file with:

API_URL="The Activity API URL"
API_KEY="Your API Key"

Usage

Start the MCP server:

npm run start

The server runs on port 3333 and provides the following MCP tools that maps to 3 of Activity API endpoints:

• getChainActivity - Get blockchain activity information for a specific chain
• getHolderStatsPerChain - Get holder counts across different chains
• getHolderInfo - Get holder information by wallet address

Configure the MCP Client (i.e. Cursor):

Create a directory called .cursor and add a file called mcp.json with the following content

{
  "mcpServers": {
    "SBC Activity API": {
      "type": "sse",
      "url": "http://localhost:3333/"
    }
  }
}

Open Cursor Settings and verify Tools are loaded.
