Attestwire MCP Server

Attestwire is an MCP integration. EN 16931: validate invoice data, UBL/CII or PDF; emit XRechnung/Peppol XML, never a PDF.

Hosted connection

The registry lists a streamable-http connection at https://api.attestwire.com/mcp. The endpoint declares these request headers: Authorization.

Packages and local setup

The published npm package is @attestwire/mcp, version 1.2.2. Its declared MCP transport is stdio.

The package declares ATTESTWIRE_API_KEY: Optional. An Attestwire API key. Six of the fourteen tools work without it; validate_invoice, validate_invoice_xml, generate_invoice, diagnose_invoice, lookup_peppol_participant, verify_vat_vies, get_recipient_profile and get_upgrade_link require one. The issue_api_key tool mints a free key (100 documents/month, no card), but minting does not authenticate a live connection: save the key, configure it here, and reconnect. Paid plans: Solo €9/mo for 1,000 documents, Starter €29/mo for 5,000, Scale €99/mo for 50,000 — get_upgrade_link returns the checkout link.; ATTESTWIRE_MCP_URL: Optional endpoint override. Defaults to https://api.attestwire.com/mcp..

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
