| Door | https://api.hanzo.ai/v1/mcp |
| Method | tools/call (JSON-RPC 2.0) |
| Arguments | 3 |
| Operation | GET /v1/books/trial |
| Product | books |
Arguments
| Field | Type | Required | Default | Values | Description |
|---|---|---|---|---|---|
from | string | — | — | — | From is the RFC3339 start of the window, exclusive. Empty means all time. |
sandbox | string | — | — | — | Sandbox reads the org's SANDBOX ledger when it is exactly "true". |
to | string | — | — | — | To is the RFC3339 end of the window, inclusive. Empty means up to now. |
tools/list declares a type and a description for each field and nothing further. A — means neither the door nor that operation constrains the field.
Call it
A tools/call carries every argument in one flat object — nothing binds to a path or a query string. Nothing above is required, so every declared argument is shown rather than a guess at which matter.
curl -X POST https://api.hanzo.ai/v1/mcp \
-H "Authorization: Bearer $HANZO_API_KEY" \
-H "Content-Type: application/json" \

}'Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.

How is this guide?
get_v1_books_transactions
ListTransactions returns the org's booked ledger as a single-line register, newest first: one row per voucher, with its date, description, vendor, category, source and amount in exact cents.
get_v1_books_vendors
ListVendors returns the org's vendor book: each canonical vendor, the alias spellings a receipt may print it under, and the expense account new bills from it default to.
