Development

git clone https://github.com/Akka-Finance/akka-mcp-server.git
cd akka-mcp-server
npm install
npm run dev        # Run with tsx (hot reload)
npm run build      # Compile TypeScript
npm start          # Run compiled output

Testing with MCP Inspector

npx @modelcontextprotocol/inspector node dist/index.js

How It Works

This MCP server is a thin client that calls the AKKA Finance REST API. It does not hold private keys or execute transactions. All swap/approve tools return unsigned transaction data that the user must sign and broadcast separately.
