Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability68
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 625 tokens (~156/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage83
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 50% of tool parameters carry a description.Partial
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the dev.invoicehub/invoicehub MCP server?

dev.invoicehub/invoicehub is a hosted endpoint at https://api.invoicehub.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 4 exposed · ~625 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
convert_invoice ~320

Convert an e-invoice between formats via the shared EN 16931 canonical model: parse the source document, re-serialize as the target, and validate the result before returning it — never a document that has not been checked. Format ids: "UBL_2.1" (OASIS UBL, the universal Peppol/EN16931 baseline), "UN_CEFACT_CII" (UN/CEFACT Cross Industry Invoice, required syntax for Chorus Pro/France and many ERP back-ends), "XRechnung_UBL" / "XRechnung_CII" (Germany's mandatory B2G format, XRechnung 3.0 — required for invoicing German public-sector buyers), "Factur-X" (France/Germany hybrid PDF+XML — a human-readable PDF/A-3 with the structured invoice embedded, common for French B2B). Binary formats (Factur-X) are base64 in both directions. Requires an API key on the Pro plan or above for any target beyond plain UBL_2.1 — call list_supported_formats to see current availability.

NameTypeReqDescription
documentstringyesThe source document: raw text for XML formats, base64 for binary formats (Factur-X).

No output schema declared.

No examples provided.

generate_invoice ~149

Generate an EN 16931-conformant UBL 2.1 invoice from structured fields. The result is self-validated before being returned. Provide seller, buyer, and at least one line; for standard-rated (category "S") lines include a vatRate and the seller vatId.

validate_invoice ~130

Validate an EU e-invoice XML string against the official EN 16931 Schematron. Accepts either syntax — UBL 2.1 (Invoice or CreditNote) or UN/CEFACT CII — and auto-detects which. A document declaring the XRechnung 3.0 CustomizationID is additionally checked against KoSIT's XRechnung delta ruleset. Returns whether it is valid and any failing BR-* / BR-DE-* business rules.

NameTypeReqDescription

No output schema declared.

Is the dev.invoicehub/invoicehub MCP server safe to use?

dev.invoicehub/invoicehub scores 78 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 dev.invoicehub/invoicehub MCP server expose?

dev.invoicehub/invoicehub exposes 4 tools: validate_invoice, generate_invoice, convert_invoice, list_supported_formats. Their descriptions and schemas cost roughly 625 tokens of context every time the server is loaded.

Does the dev.invoicehub/invoicehub MCP server require authentication?

No. We connected to dev.invoicehub/invoicehub without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the dev.invoicehub/invoicehub MCP server still maintained?

dev.invoicehub/invoicehub is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
