Overview

AI-generated overview

Remote MCP endpoint that validates EN 16931 and XRechnung e-invoice XML and issues signed Ed25519 verifiable credentials.

What you can do
  • Validate EN 16931 and XRechnung e-invoice XML through the hosted validator.
  • Receive signed Ed25519 verifiable credentials as validation output.
  • No tool list is published, so the exact operations are not documented; the description only names validation and credential issuance.
When to use it
Useful when an assistant needs to check whether an e-invoice XML file conforms to EN 16931 or XRechnung and to obtain a signed proof of the result, for example in invoicing or compliance workflows.
Requirements
A remote streamable HTTP endpoint; no package installation, environment variables or headers are declared. The manifest declares no authentication, so no account or API key is documented.
Before you install
Invoice XML is sent to a third-party hosted service; the description states zero retention, but this is the provider's own claim. The manifest declares no authentication, so anyone with the endpoint can call it. Signed credentials are issued by the provider, so their trust depends on that provider.

Installation

In SourceWeft

  1. Open EU EN-16931 & XRechnung Deterministic Validator in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/eu.iotpay%2Fen16931-validator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
