ArihantPlus MCP itself is completely free - no charges from our end at all.  

The one thing you might need is an active paid subscription of the AI assistant. Some AI platforms do now allow adding custom MCP on a free account. You need to have a paid account to connect ArihantPlus MCP. However, for now this feature is available for free on Claude. You can learn how to connect your ArihantPlus trading account with Claude here.
