How do I install Attestwire?

Copy the http config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Attestwire need an API key?

The publisher lists these environment variables: ATTESTWIRE_API_KEY, ATTESTWIRE_MCP_URL.

What transport does Attestwire use?

Attestwire is reached over HTTP.

Attestwire

by com.attestwire

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

Power your agent

Add this server

The publisher's own URL. Not a PlugMCP endpoint.

Server URL

https://api.attestwire.com/mcp

Credentials from the publisher

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.
