Check a supplier's new bank details, an IBAN or a Peppol address before you pay an invoice.
Five free tools, no account: check an IBAN's structure and check digits (70+ countries, offline; it never says who owns the account), check a supplier's bank-detail change before paying (no_change, verify_first or stop, with call-back steps), compare what was approved with what is about to be paid, check an invoice against published Peppol rules, and ask the Peppol registers whether a company can receive e-invoices. EU VAT lookup and invoice review are paid and need a token. Jithox never moves money and never says an account is safe.
Try asking Muse: "Check if a customer's VAT number is valid and generate a Peppol-ready e-invoice to send them."

Jithox is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

It never claims the account exists or who owns it. Free, no token.check_peppol_readyCheck your own invoice against 21 published Peppol BIS Billing 3.0 rules, and whether the customer's Peppol address is registered; each finding names the rule and the fix.

Free, no token.lookup_peppol_participantAsk live Peppol registers about e-invoice reception, document types and failure contacts; never guarantees delivery. Not a VAT or company-register check; use kbo_company_search (one company) or check_vat_list (a list).
