Access and downloads
Guidance, requirements and record checks are free and need no account. Downloads cost ₹499 + GST once per GSTIN and refund period, including both files and further downloads after you correct your entries.
Connect your Fast GST Refund account through OAuth for direct downloads when you have access for that GSTIN and period. Otherwise, the generator returns a browser link: open it, sign in by email and complete the download on the website. Both files can share one link, which lasts 24 hours. Payment is completed by the user on the website; the assistant cannot charge a card or access billing details.
The taxpayer reviews the records and uploads the generated files to the GST portal. The service does not log into the GST portal or file applications. Use only the validation and generation tools' documented fields with the taxpayer's permission. Keep identifiers and source documents out of the five guidance/arithmetic tools.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
