Ibanchecker tools (5)

write = sends, deletes, buys or posts
  • extract_ibans_from_textFree

    Scan a free-form block of text and pull out every candidate IBAN, then validate each one. Useful for unstructured sources such as emails, invoices, PDFs pasted as text, or chat messages where IBANs appear inline and may be split by spaces or surrounded by other words. Returns JSON with `count`, `valid_count`, `invalid_count` and `results`, one `validate_iban`-shaped entry per IBAN found; text containing no IBAN returns an empty list rather than an error. Use this as the first step when the account number is buried in prose; pass the extracted IBANs to `validate_bulk_ibans` only if you need to re-check them separately. Input text is processed in memory and not stored. Requires an API key on the Growth plan or above; a free key whose address has a verified ibanchecker.cash account can try it with up to 5,000 characters per call. Each IBAN found counts as one request.

  • get_iban_formatFree

    Return the IBAN format specification for a country, covering 92 supported IBAN-using countries. Returns JSON describing the country's total IBAN length, the BBAN layout (bank code, branch code, and account number positions and lengths), an example IBAN, and the SEPA-membership flag. Use this to understand or display how a country's IBAN is structured, to build input masks, or to explain a validation failure, not to validate a specific number (use `validate_iban` for that). An unsupported or unknown country code returns an error result describing the problem. Works without an API key, up to 100 requests an hour per IP.

  • lookup_bicFree

    Look up a financial institution by its BIC (Business Identifier Code, also called SWIFT code) and return the matching bank's details. Accepts an 8-character (head office) or 11-character (branch) BIC. Returns JSON with `bic`, `bic8`, `bank_name`, `city`, `country_code`, `country_name`, `sepa`, the institution `type` and its `status`. Use this to resolve a BIC to a human-readable bank, to confirm a SWIFT code is real, or to enrich a validated IBAN with institution details. An unknown or malformed BIC returns an error result rather than a guess; codes are never fabricated. Requires an API key on the Basic plan or above, or a free key whose address has a verified ibanchecker.cash account.

  • validate_bulk_ibansFree

    Validate a batch of up to 100 IBANs in one call, applying the same ISO 13616 checks as `validate_iban` (country, length, BBAN structure, MOD-97). Returns JSON with `count`, `valid_count`, `invalid_count` and `results`, one entry per IBAN in input order, each shaped like a `validate_iban` result. Use this instead of calling `validate_iban` in a loop when checking a list (e.g. a payment file or a column of supplier accounts). Split inputs larger than 100 into multiple calls. Account numbers are validated in memory and never stored. Requires an API key on the Basic plan or above; a free key whose address has a verified ibanchecker.cash account can try it with up to 10 IBANs per call. Each IBAN counts as one request.

  • validate_ibanFree

    Validate a single International Bank Account Number (IBAN) against the official ISO 13616 structure for its country. What it checks: the country code, total length for that country, the national BBAN structure, and the MOD-97 check digits. When the bank/branch code maps to a known institution, the response also includes the bank name, BIC/SWIFT code, and country. Returns JSON with `valid` (boolean), `iban`, `formatted`, `country`, `country_name`, `check_digits`, `bban`, and, when the bank is recognized, `bank_name`, `bic`, `bank_code`, `bank_city`, `sepa` and `national_check_valid`. An invalid IBAN still returns a result, with `valid: false`, an `error` message and an `error_code` (e.g. INVALID_CHECKSUM, INVALID_LENGTH, UNKNOWN_COUNTRY); it does not throw. Use this when you have one account number to verify. For many IBANs prefer `validate_bulk_ibans`; to pull IBANs out of prose use `extract_ibans_from_text` first. No account data is stored; validation runs in memory and is discarded. Requires an API key; a free key from ibanchecker.cash/api-docs covers 100 requests a month.

What the publisher says

From the Ibanchecker repository's README, as published. We do not edit it. Read it on GitHub

ibanchecker-mcp

MCP (Model Context Protocol) server for ibanchecker.cash. Gives AI assistants like Claude five finance tools backed by the ibanchecker.cash validation engine:

No IBAN data is logged or stored; validation runs in memory on Cloudflare's edge. See the security page for details.

Quick start: hosted remote server

The easiest path is the hosted endpoint. Nothing to install or deploy.

https://mcp.ibanchecker.cash/mcp

Claude Code

claude mcp add --transport http ibanchecker https://mcp.ibanchecker.cash/mcp

Claude Desktop (claudedesktopconfig.json), via the mcp-remote bridge:

{
  "mcpServers": {
    "ibanchecker": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.ibanchecker.cash/mcp"]
    }
  }
}

Local stdio server

Run the server locally over stdio (requires Node 18+):

{
  "mcpServers": {
    "ibanchecker": {
      "command": "npx",
      "args": ["-y", "@ibanchecker/mcp"],
      "env": {
        "IBANCHECKER_API_KEY": "your-api-key-here"
      }
    }
  }
}

Example

Calling validate_iban with DE89370400440532013000 returns:

{
  "valid": true,
  "iban": "DE89370400440532013000",
  "formatted": "DE89 3704 0044 0532 0130 00",
  "country_name": "Germany",
  "bank_name": "Commerzbank AG Cologne",
  "bic": "COBADEFFXXX",
  "bank_code": "37040044",
  "account_number": "0532013000",
  "sepa": true
}

When the API returns an error (for example a 429 rate limit or 401 bad key), the tool result is flagged with isError: true and a human-readable message, so the assistant can react rather than crash.

API key

The underlying REST API has a free tier (1,000 requests/month). Get a key at ibanchecker.cash/api-docs and pass it as:

  • IBANCHECKERAPIKEY env var (stdio mode), or
  • Authorization: Bearer / x-api-key header (remote mode).

Project layout

.
├── bin/stdio.mjs      # npm CLI entry (published as `ibanchecker-mcp`)
├── shared/tools.mjs   # the 5 tool definitions, shared by both transports
└── worker/            # Cloudflare Worker (the hosted remote server)
    ├── src/index.ts
    └── wrangler.toml

Both the stdio CLI and the Worker register the exact same tools from shared/tools.mjs, so there is a single source of truth.

Self-hosting the Worker

The remote server is a Cloudflare Worker built on the Agents SDK. Deploy your own:

cd worker
npm install
npx wrangler deploy

Remove the routes block in worker/wrangler.toml (or point it at your own domain) and optionally set a server-wide key with npx wrangler secret put IBANCHECKERAPIKEY.
