The guide catalog is also available as the MCP resource gstrefund://guides. See the MCP setup and worked example.

Use the Codex plugin

Download version 1.0.1 and follow the local installation guide. The package includes the preparation skill and MCP connection. Directory review and publication are separate from local installation.

Free preparation pack

The free preparation pack includes Statement 3 and Annexure B working templates, an offline allocation checker, worked examples and a reviewer checklist. Download it without an account, email address or payment; keep completed working locally.

Inputs and usage

Keep taxpayer identifiers, credentials and document contents local. Allocation inputs use positive row numbers and integer INR paise, with up to 200 invoices, 200 receipts and 1000 allocations per check. The server limit is 60 requests per minute per IP; a 429 response includes a retry interval.

Operational metrics record tool names, outcomes and timings, excluding inputs and outputs. Set X-GST-Analytics: off to disable these metrics. The plugin declares its distribution source with X-GST-Client: codex-plugin; this is not authenticated identity. See privacy and support.

What you can do

Fast GST Refund is building a self-serve preparation product that brings source imports, reconciliation, exception review, Rule 89(4), Statement 3 and Annexure B into one workflow. Early access is not open yet.

Find records to gather, checks to make and relevant reading for Indian service-export GST refunds under LUT. The checklist covers Statement 3, Annexure B, reconciliation and preparation for the portal, with separate guidance for upload problems, filed claims and notices.

The tools support preparation and review. Keep final tax decisions and filing with the taxpayer and their authorised reviewer.
