@Dandeliongold/ Time

An MCP server for getting current time in ISO format (YYYY-MM-DD HH:mm:ss) using JavaScript Date. This server works with the Claude desktop app on both Windows and macOS.

Components

Tools

1. getCurrentTime

   • Returns the current time in ISO format
   • No input parameters required
   • Returns:

     {
       "time": "2024-02-08 11:04:33",
       "success": true
     }
     

   Example JSON-RPC request:

   {
     "jsonrpc": "2.0",
     "id": 1,
     "method": "getCurrentTime"
   }
   

   Example JSON-RPC response:

   {
     "jsonrpc": "2.0",
     "id": 1,
     "result": {
       "time": "2024-02-08 11:04:33",
       "success": true
     }
   }
   

2. getTimeDifference

   • Calculates the time difference between a given timestamp and the current time
   • Parameters:
     • timestamp: ISO format timestamp (YYYY-MM-DD HH:mm:ss)
     • interval: 'minutes' (default) or 'seconds'
   • Returns a signed difference value following this convention:
     • Positive values (+) indicate future timestamps ("in X minutes/seconds")
     • Negative values (-) indicate past timestamps ("X minutes/seconds ago")
     • Zero (0) indicates same timestamp

   Example JSON-RPC request:

   {
     "jsonrpc": "2.0",
     "id": 1,
     "method": "getTimeDifference",
     "params": {
       "timestamp": "2024-02-08 12:30:00",
       "interval": "minutes"
     }
   }
   

   Example JSON-RPC responses:

   // For a past timestamp (30 minutes ago)
   {
     "jsonrpc": "2.0",
     "id": 1,
     "result": {
       "difference": -30,
       "interval": "minutes",
       "inputTimestamp": "2024-02-08 12:30:00",
       "currentTime": "2024-02-08 13:00:00"
     }
   }
   
   // For a future timestamp (in 45 minutes)
   {
     "jsonrpc": "2.0",
     "id": 1,
     "result": {
       "difference": 45,
       "interval": "minutes",
       "inputTimestamp": "2024-02-08 13:45:00",
       "currentTime": "2024-02-08 13:00:00"
     }
   }
   

Features
