lookup_tax_rate
shallowio.github.HelloBooksAIAgents/hellobooks-mcp · Verify this server
Pick a single statutory tax-rate slab — either by exact `id` (e.g. `IN-standard-18`, `GB-zero-0`, `CA-hst-13-on`) for a deterministic lookup, or by `country` + free-text `category` (e.g. "office supplies", "restaurant", "exports", "domestic fuel") for a fuzzy best-match. Returns the matched rate, the match score, and the authoritative `source` URL. Use this when a user asks "what slab does X fall into in India?" or "what VAT rate applies to children's car seats?". For broader exploration (all slabs in a country / all rates of one scheme), use list_tax_rates. No customer data — public statutory reference only.
