sepa-validator-mcp

Stdio MCP server, version 0.2.0. Tools: validate_sepa (POST https://checksepa.com/v1/validate), camt_validate (POST https://checksepa.com/v1/camt/validate), and camt_convert (POST https://checksepa.com/v1/camt/convert, format json or csv).

Input: exactly one of file_path (read by this process) or xml (the document as a string).

Output: valid, format, version, errors[], and warnings[]. Each finding has code, message, path, and line (line is an integer or null).

validate_sepa covers pain.001.001.03 and pain.001.001.09. camt_validate and camt_convert cover camt.053 and camt.054 versions .02 and .08. pain.008 is recognised by validate_sepa and returned with valid: false. The three routes share the free limit.

Free limit: 30 requests per IP per hour, 200 per UTC day, 2 MB. The file is not stored. The tool calls the network, so it is not a local read-only check. Higher limits and API keys: https://checksepa.com/api-waitlist
