## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 71/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 396 tokens (~79/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `generate_invoice` (~113 tokens)

Generate a compliant e-invoice

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.

Input parameters:

- `invoice` (object, required): The invoice to produce
- `profile` (string): Which specification identifier to stamp on the document

### `validate_invoice` (~109 tokens)

Check an invoice against EN 16931 rules

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.

Input parameters:

- `invoice` (object, required): The invoice to check, however incomplete

### `extract_invoice` (~79 tokens)

Read an invoice document into structured data

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.

Input parameters:

- `xml` (string, required): The invoice XML, UBL 2.1 or CII

### `describe_coverage` (~65 tokens)

List what this server checks and what it does not do

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.

### `get_usage` (~30 tokens)

Get usage and credit balance

Returns your current plan, remaining credit balance and call volume over the last 30 days. Free to call.

## Common questions

### What is the InvoiceForge MCP server?

InvoiceForge is an MCP server listed in the public MCP registry as com.agenttoolworks/invoiceforge. Generate, validate and read EN 16931 and Peppol BIS 3.0 e-invoices, in UBL and CII. This page covers its hosted endpoint (https://invoiceforge.agenttoolworks.com/mcp).

### Is the InvoiceForge MCP server safe to use?

InvoiceForge scores 85 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the InvoiceForge MCP server expose?

InvoiceForge exposes 5 tools: generate_invoice, validate_invoice, extract_invoice, describe_coverage, get_usage. Their descriptions and schemas cost roughly 396 tokens of context every time the server is loaded.

### Does the InvoiceForge MCP server require authentication?

Yes. InvoiceForge asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the InvoiceForge MCP server still maintained?

InvoiceForge is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
