Available tools 11

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

refund

get_refund_checklist

Returns the records to gather, the checks to make, the next step and the relevant guides for one stage of a service-export GST refund claim and one preparation topic. Use it when someone asks what to prepare or check.

read_refund_guide

Returns one public guide as Markdown, with its source links and the date its sources were checked. Takes a slug from search_refund_guides.

search_refund_guides

Finds Fast GST Refund's public guides by preparation topic and returns their slugs, titles and descriptions. Takes general keywords; it does not need taxpayer identifiers or document contents.

generate

generate_annexure_b

Creates the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, from records that pass validate_annexure_b. Returns openUrl, a link the user opens in a browser to sign in by email, pay once per GSTIN and refund period, and download; the checked records are stored behind the link for 24 hours. With a connected account that has paid, it returns the file. The tool takes no GST portal password or OTP. ITC eligibility, reversal amounts and GSTR-2B periods come from the taxpayer's reviewed records; the tool does not infer them.

generate_statement3

Creates the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, from records that pass validate_statement3. Returns openUrl, a link the user opens in a browser to sign in by email, pay once per GSTIN and refund period, and download; the checked records are stored behind the link for 24 hours. With a connected account that has paid, it returns the file. The tool takes no GST portal password or OTP.

validate

validate_annexure_b

Checks records for the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility. Applies the offline utility's own checks and returns every error and warning at once, with its row and field. Free; needs no sign-in; stores nothing. A file made by the official utility can be passed as data unchanged. ITC eligibility, reversal amounts and GSTR-2B periods come from the taxpayer's reviewed records; the tool does not infer them.

validate_statement3

Checks records for the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility. Applies the offline utility's own checks and returns every error and warning at once, with its row and field. Free; needs no sign-in; stores nothing. A file made by the official utility can be passed as data unchanged.

annexure

get_annexure_b_requirements

Returns the fields of the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, and where each value comes from: purchase documents, tax amounts, the GSTR-2B period, reviewed ITC eligibility and the eight GSTR-3B reversal totals, with the fields each supply type leaves empty. Takes no input. Use it before validate_annexure_b to learn which fields to collect.

explain

explain_upload_error

Returns the documented checks and correction steps for one known problem with a Statement 3 or Annexure B file. Statement 3 issues: json_generation, receipt_allocation, corrected_retry, return_mismatch. Annexure B issues: duplicate_document, gstr2b_mismatch, reversals, json_generation.

receipt

check_receipt_allocation

Checks how bank receipts are allocated to export invoices: arithmetic, duplicate allocations, missing row references, overallocated receipts and invoice balances. Takes anonymous row numbers and integer INR paise only; names, GSTINs and certificate numbers are not needed. Up to 200 invoices, 200 receipts and 1000 allocations.

statement3

get_statement3_requirements

Returns the fields of the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, and where each value comes from: export invoices and notes, bank BRC/FIRC rows, and shipping details for goods. Takes no input. Use it before validate_statement3 to learn which fields to collect.

Fast GST Refund — questions

Answers built from our own checks of this server.

What can Fast GST Refund do?

It exposes 11 tools, read directly from the server on our last check. Among them: check_receipt_allocation, explain_upload_error, generate_annexure_b, generate_statement3, get_annexure_b_requirements, get_refund_checklist and 5 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Fast GST Refund mostly used for?

Its tools cluster around refund, generate and validate. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Fast GST Refund working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 228 ms. The bar chart above shows every period we have measured.

How do I connect Fast GST Refund?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Fast GST Refund need an API key?

No. Fast GST Refund completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Fast GST Refund?

It answers our handshake in 228 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Fast GST Refund open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
