IBANforge 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

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
validate_ibanVerify whether an IBAN from any of the 89 IBAN countries is valid AND enrich it with bank, compliance and routing data. USE WHEN: the user mentions an IBAN, asks to validate an IBAN and identify the issuing bank, asks to detect a typo in an IBAN, asks who the bank is behind an IBbatch_validate_ibanValidate up to 100 IBANs in a single call. Paid per call in USDC via x402, it costs $0.002 per IBAN instead of $0.005 per validate_iban call; on an API key or a credit pack each IBAN uses one request or credit, the same as one validate_iban call. USE WHEN: the user pastes a list lookup_bicResolve a BIC / SWIFT code into the underlying bank: name, country, city, LEI, and registered head-office address (where available). USE WHEN: the user already has a BIC/SWIFT (8 or 11 chars, alphanumeric, e.g., "UBSWCHZH80A", "DEUTDEFF") and asks which bank it belongs to, where check_complianceRun a pre-flight compliance triage on an IBAN before sending a SEPA / cross-border payment. USE WHEN: the user is about to send a payment / payout / refund and wants to triage risk first, asks whether the payee's bank or its country is under sanctions, asks if a SEPA Instant tranvalidate_payment_referenceValidate a structured payment reference and, when an IBAN is supplied, decide whether the two may legally travel together.

USE WHEN: a result looks wrong, datrequest_api_keyStart the process that gives your human a free IBANforge API key, without any e-mail address. The key does not unlock this session: it works once your human puts it in the MCP client configuration and reconnects, or sends it to the REST API, so tell them where it goes when you hapoll_api_keyCollect the API key once a human has approved the request opened by request_api_key.

At the last check (November 13, 2026, 09:31 UTC) the endpoint was working, answering in 642ms. Over the last 7 days it answered 100% of health checks. It is checked every 15 minutes.
It was screened on September 25, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 11 tools, including validate_iban, batch_validate_iban, lookup_bic, check_compliance. For example, you could ask Muse: "Check if this IBAN is valid and whether the bank is under sanctions before I send a payment."
