## Findings

No check matched anything in these tool definitions.


## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_emi`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Monthly EMI on a reducing-balance loan, total interest, total payment and the year-by-year schedule. Read-only arithmetic.
```

### `calculate_gst`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
GST on an amount in rupees: add GST to an amount before tax, or take it out of an amount that includes it; CGST + SGST for a supply within one state, IGST across states. Read-only arithmetic.
```

### `calculate_vat`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
VAT on an amount: add it to a net amount or take it out of a gross one. UK by default; EU countries and the UAE by country (standard rate if no rate is given). Read-only arithmetic.
```

### `check_gstin`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Checks that an Indian GSTIN is well formed (15 characters, state code, PAN, check character) and decodes the state and PAN. It makes no lookup and does not confirm that the registration exists or is active. Read-only.
```

### `create_document_link`

- The name "create_document_link" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Validates a document (invoice, quote, proforma invoice, receipt or credit note) and returns editor_url, a short link that opens it prefilled in the LuckPanda editor, where the person can review, edit and download the PDF. Also returns the totals with tax worked out, the required fields still missing and any parts left out as invalid. Side effect: the document is stored on LuckPanda's servers for 7 days under a random link id (not listed or indexed), and every call creates a new link. Nothing is issued, numbered or sent. Use details the person gave; do not invent them.
```

### `create_document_pdf`

- The name "create_document_pdf" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generates a PDF of a document (invoice, quote, proforma invoice, receipt or credit note) and returns it base64-encoded in structuredContent.pdf_base64, with its verification URL and an editor_url that opens the same document in the editor. PDFs from this tool include a LuckPanda footer and a verification QR code. Side effects: stores a verification record for the PDF (issuer name, document type, date, currency and total; no client details) and a 7-day copy of the document behind editor_url. Limit: about 40 PDFs an hour per network.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `find_hsn_code`

- The name "find_hsn_code" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Searches HSN codes (goods) and SAC codes (services) by product or service words or by code digits, with the official description, the chapter and heading it sits under, and the GST rate where it has been checked against the rate notification (otherwise rate_percent is null: check the notification). Returns the dataset scope with every answer. India only.
```

### `get_document_rules`

- The name "get_document_rules" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns what to collect before creating a document of a given type and country: required, recommended and optional fields, the tax ID and tax names, the country's invoicing rules (for example India GST rule 46, UK VAT invoice contents), the CGST/SGST versus IGST split and state codes for India, and credit-note reasons. Read-only.
```

### `list_tools`

- The name "list_tools" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the document pages on luckpanda.app (generators for invoices, quotes, proforma invoices, receipts and credit notes, plus country and trade templates) and its calculator pages, each with its URL. Optional filters: document_type, country, query. Read-only.
```
