### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

- n/a `auth.secret_in_url`: no templated URL

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 997 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: n/a (weight 15)

## Tools (2)

- `check_invoice_math`: Use this when the user types or pastes invoice amounts (line quantities, unit prices, line amounts, subtotal, discount, tax, shipping, total) and wants to know whether the invoice adds up. Returns PASS, MISMATCH with the difference in cents, or NOT CHECKABLE when a value is missing, for three checks: lines add up to the subtotal, subtotal - discount + tax + shipping = total, quantity x unit price = amount. Uses integer cent math. Does not read files (use read_invoices for PDFs), does not compute tax rates, and does not pay or send anything.
- `read_invoices`: Use this when the user attaches 1 to 20 invoice PDFs and wants them in a spreadsheet, wants invoice data extracted (vendor, invoice number, invoice date, due date, subtotal, tax or VAT or GST, shipping, discount, total, amount due, line items), or wants the invoice arithmetic checked. Returns one Excel workbook (Invoices and Line items sheets) and a ZIP of CSV files, plus per-invoice checks: lines add up to the subtotal, subtotal - discount + tax + shipping = total, quantity x unit price = amount. Each check is PASS, MISMATCH with the difference, or NOT CHECKABLE when a value is missing. Text-based PDFs only (no OCR), up to 10 MB and 20 pages per file. Does not pay, approve, or send invoices. Do not use for receipts photographed with a phone or for making a new invoice.
