• src/tools/misc.py:30-48 (handler)

  Handler for the 'type' tool: retrieves the Redis data type, TTL, and key info using r.type(key). Registered via @mcp.tool() decorator.

  @mcp.tool()
  async def type(key: str) -> Dict[str, Any]:
      """Returns the string representation of the type of the value stored at key
  
      Args:
          key (str): The key to check.
  
      Returns:
          str: The type of key, or none when key doesn't exist
      """
      try:
          r = RedisConnectionManager.get_connection()
          key_type = r.type(key)
          info = {"key": key, "type": key_type, "ttl": r.ttl(key)}
  
          return info
      except RedisError as e:
          return {"error": str(e)}
