UK building calculators, estimate comparisons and account-scoped quoting and job costs.
Scored across 31 tools
The set follows a very clear resource×action matrix, and the prepare_*/send_* pairs are explicitly distinguished (preview vs. actual send). Minor overlap exists where get_job_financials returns aggregate totals that get_estimate, get_quote and list_invoices also expose individually, and where prepare_calculation/discover_calculators/run_calculation could be momentarily conflated, but descriptions resolve this.
Every tool uses snake_case with a leading verb (create_, get_, list_, add_, prepare_, send_, record_, run_, review_, attach_, compare_, discover_) followed by a clear resource noun. The pattern is predictable and uniform across all 31 tools.
The domain genuinely spans jobs, estimates, quotes, invoices, variations, files, calculations and billing, so breadth is warranted. However, 31 tools is heavy, and the three parallel prepare_*/send_* pairs plus separate draft/get/list tools per document type inflate the surface where consolidation could reduce cognitive load.
Coverage is strong: full prepare→send→record lifecycle for invoices, quotes and variations, plus estimate versioning, job costs, files, calculations and reporting. Gaps remain in mutation/lifecycle operations — no update or delete for jobs, drafts, or files, and no dedicated list_quotes/list_estimates (only reachable via job financials).

Inputs: quoteId (required). Returns: ok, data, error, warnings, +3 more
Lists invoices belonging to one owned job.
Inputs: jobId (required). Returns: ok, data, error, warnings, +3 more
Lists job photos and files without exposing private storage credentials.
Inputs: jobId (required). Returns: ok, data, error, warnings, +3 more
Lists the signed-in user’s jobs. Client contact details and full addresses are omitted unless clients:read is granted.
Inputs: limit, status. Returns: ok, data, error, warnings, +3 more
Lists variations belonging to one owned job.
Inputs: jobId (required). Returns: ok, data, error, warnings, +3 more
Returns the exact questions and typed inputs required before a deterministic calculation can run.
Inputs: calculatorId (required), supplied. Returns: ok, data, error, warnings, +3 more
Shows the exact unpaid invoice and records a one-use ten-minute confirmation. It does not mark the invoice paid.
Inputs: invoiceId (required), paymentMethod (required), idempotencyKey (required), expectedVersion (required), +3 more. Returns: ok, data, error, warnings, +3 more
Previews the exact current invoice recipient and payload, then stores a one-use ten-minute confirmation token. This does not send.
Inputs: invoiceId (required), idempotencyKey (required), expectedVersion (required). Returns: ok, data, error, warnings, +3 more
Creates a one-time, ten-minute secure image upload for a supplier receipt, customer payment proof or job evidence. Uploading proof never marks an invoice as paid.
Inputs: kind (required), jobId (required), fileName (required), fileSize (required), +5 more. Returns: ok, data, error, warnings, +3 more
Previews the exact current quote recipient and payload, then stores a one-use ten-minute confirmation token. This does not send.
Inputs: quoteId (required), idempotencyKey (required), expectedVersion (required). Returns: ok, data, error, warnings, +3 more
Previews the exact current variation recipient and payload, then stores a one-use ten-minute confirmation token. This does not send.
Inputs: variationId (required), idempotencyKey (required), expectedVersion (required). Returns: ok, data, error, warnings, +3 more
Marks the exact prepared invoice as paid only after an explicit, one-use confirmation. It never contacts the customer or payment provider.
Inputs: invoiceId (required), idempotencyKey (required), confirmationToken (required). Returns: ok, data, error, warnings, +3 more
Checks line completeness, unresolved scope and zero rates without changing the estimate. This does not establish construction scope completeness or readiness to quote.
Inputs: items (required). Returns: ok, data, error, warnings, +3 more
Runs one versioned QuoteBuild formula. Missing inputs use disclosed example defaults; confirm them and labour inclusion before drafting. Rates are baseline allowances. The model must not calculate monetary totals itself.
Inputs: values (required), calculatorId (required), pricing. Returns: ok, data, error, warnings, +3 more
Creates a new immutable estimate version; it never overwrites the last valid version.
Inputs: items (required), jobId (required), idempotencyKey (required), label, +7 more. Returns: ok, data, error, warnings, +3 more
Sends the exact prepared invoice payload after validating the one-use confirmation token.
Inputs: invoiceId (required), idempotencyKey (required), confirmationToken (required). Returns: ok, data, error, warnings, +3 more
