Steps to use and Tech Stack:-

• This project is simple TS-MCP server which uses pnpm for dependency management.
• Steps to use this server:-
  • Clone the repo to your local machine.

  • Run pnpm build command. This creates dist/src/index.js file which will be used as MCPServer.
  • Add below config to claude_desktop_config.json file:-

      "currencyrate": {
      "command": "node",
      "args": [
        "/Users/sripadt/Projects/CurrencyRate-MCP/dist/src/index.js"
      ]
    }

  • With this step, MCPServer is available for usage with Claude desktop.

  Steps to run MCP server manually:-

  • If you wish to debug this using MCPInspector, you can run the command pnpm dlx @modelcontextprotocol/inspector
    • This opens up MCPInspector UI on http://127.0.0.1:6274/ where you need to specify node as command to run with dist/src/index.js as argument. This gives us UI to connect with out mcp server for debugging.
