ISO 20022 MCP Server

The Model Context Protocol (MCP) lets your AI assistant generate and validate your credit transfer and direct debit files for you. Describe your payments in natural language, get back XSD-validated, bank-ready XML.

Included in the multi (200 generations/month) and business (1,000 generations/month) plans.

Create my API key

Get started in 3 steps

1. Create your API key

From your account page, create a personal API key. It is shown exactly once: store it somewhere safe.

2. Add the server to your assistant

One command for Claude Code; a configuration block for Cursor or ChatGPT. Examples below.

3. Generate in natural language

"Generate a pain.001 with these 12 transfers" — the assistant calls the server, which returns XML validated against the official schema.

Per-client setup

Claude Code

In a terminal, add the server with your key:

claude mcp add --transport http iso20022 https://mcp.iso20022generator.com/mcp --header "Authorization: Bearer YOUR_API_KEY"

Cursor

Add this block to your ~/.cursor/mcp.json (or via Settings → MCP):

{
  "mcpServers": {
    "iso20022": {
      "url": "https://mcp.iso20022generator.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

ChatGPT

In ChatGPT (developer mode), add an MCP server with this URL and the Authorization: Bearer YOUR_KEY header:

https://mcp.iso20022generator.com/mcp

Available tools

generate_sepa_xml

Generates SEPA pain.001 (credit transfer) or pain.008 (direct debit) XML, validated against XSD + banking rules (IBAN, EndToEndId, charset).

validate_sepa_xml

Validates an existing XML against the official schema and blocking business rules. Open to all plans.

generate_mt103

Generates a SWIFT MT103 message (international wire, text format). Business plan only.

Every generation response includes your remaining quota (used/limit). Validation never consumes quota.
