Brand new validation library
We’re announcing a new package today: BeneficialStrategies.Iso20022.FluentValidation, the validation companion to the C# ISO 20022 library. It’s on NuGet now, and it’s up to date with the same June 26, 2026 specification snapshot as the library it validates. Up front: this is a work in progress, not a finished product. It already covers real ground — enough to fully validate two entire business areas — but large parts of the specification aren’t built out yet. We’d rather ship what’s solid and be honest about what isn’t than wait until everything is done. Below is exactly where that line sits today.
C# ISO 20022 Library updated to June 2026 snapshot
Right alongside the MCP server’s own update to the June 26, 2026 ISO 20022 snapshot, we’ve brought the C# ISO 20022 Library — our free, open, .NET implementation of the standard — up to date as well. It now covers 3,311 message types from the current specification, with full XML and JSON serialization for each one. If you’ve never run across it: this is a from-scratch .NET class library that turns the ISO 20022 specification into strongly-typed, IntelliSense-friendly C# — records and structs the compiler actually helps you use correctly, instead of a loose bag of XML you have to trust yourself to get right.
How Do I Implement the ISO 20022 Digital Signature?
A C# developer implementing ISO 20022 message signing asks the MCP Server to explain SignatureEnvelope and SignatureEnvelopeReference — and walks away with working code for both origination and verification.
What ISO 20022 Message Pays a Merchant for Two Invoices — With Full Lifecycle Tracking?
A live demonstration of the Beneficial Strategies AI MCP Server: a plain-English question about paying a merchant for two invoices produces spec-accurate XML, an ISO-aligned database model, a state diagram, and a full C# MassTransit Saga — automatically.
Powerpoint Anyone?
The Beneficial Strategies AI MCP Server helps a development manager create a complete PowerPoint training deck on remt.001 — slides, speaker notes, diagrams, and C# generation code — from a single plain-English request.
QA Needs AI Help Too
Watch the Beneficial Strategies AI MCP Server help a QA manager build a rigorous, spec-grounded test plan for tsmt.053 and tsmt.054 — from a single plain-English request.
What ISO 20022 Message Sends an Invoice to a Customer?
A live demonstration of the Beneficial Strategies AI MCP Server: one plain-English question produces the message identification, a real XML sample, and a complete C# data container — automatically.

Progress report 1
I had time to give the site a bit of an uplift, but it still needs a lot of work. I’ve been working instead with a new and emerging technology. You may not know it, but the entire world agreed several years ago on a new standard for messaging in the business services arena. The ISO20022 standard has been in-process for many years, but most financial institutions are not ready to use it. Additionally, since digital currencies like Ripple XRP and Stellar Lumens XLM are making it possible to send fully-settled payments corp-to-corp without involving a financial instituion at all.
