A4.4/5.0
Scored across 5 tools
Disambiguation5/5
Each tool has a clearly distinct role: describe_coverage (capability metadata), extract_invoice (parse/ingest), generate_invoice (produce XML), validate_invoice (rule checking), and get_usage (account info). None overlap in purpose or action.
Naming Consistency5/5
All five tools follow a consistent verb_noun snake_case pattern (describe_coverage, extract_invoice, generate_invoice, validate_invoice, get_usage). No mixing of conventions or vague standalone verbs.
Tool Count5/5
Five tools is a well-scoped set that covers the essential invoice lifecycle operations plus a capability-discovery tool and an account/usage tool. Nothing feels redundant or padded.
Completeness4/5
The surface covers reading (extract), writing (generate), checking (validate), docs (describe_coverage), and account (get_usage), which is solid. Minor gaps: generate only outputs UBL 2.1 while extract reads both UBL and CII, so there is no syntax-conversion path back to CII/Factur-X, and no batch operation.
Available Tools
5 toolsdescribe_coverageList what this server checks and what it does not doAInspect
Returns the exact EN 16931 rules this server checks, the syntaxes it can produce and read, and the things it deliberately does not do, such as transmitting invoices over Peppol or acting as a French accredited platform. Light read: costs 0.2 credit.
Inputs: no named parameters.
extract_invoiceRead an invoice document into structured dataAInspect
Reads an incoming UBL or CII (Factur-X) invoice XML and returns the data as structured JSON, listing any field the document did not contain rather than guessing it. Use it to ingest supplier invoices before booking them. Costs 1 credit.
Inputs: xml (required).
generate_invoiceGenerate a compliant e-invoiceAInspect
Turns invoice data into a compliant UBL 2.1 XML document following the EN 16931 semantic model, with totals and the VAT breakdown computed for you. Choose the plain EN 16931 profile or the Peppol BIS Billing 3.0 customization. The document is validated before it is returned, so you never get back XML that would be rejected. Costs 1 credit.
Inputs: invoice (required), profile.
get_usageGet usage and credit balanceAInspect
Returns your current plan, remaining credit balance and call volume over the last 30 days. Free to call.
Inputs: no named parameters.
validate_invoiceCheck an invoice against EN 16931 rulesAInspect
Checks invoice data against a documented subset of the EN 16931 business rules: mandatory fields, code lists, VAT category consistency and the arithmetic that most often gets invoices rejected. Accepts incomplete or malformed data on purpose, since that is what you want checked, and answers with each violation, its rule identifier and its business term, plus exactly which rules were checked. It never claims full compliance with the norm. Costs 1 credit.
Inputs: invoice (required).
