AskISO is an independent open-source project for ISO 20022 messaging. Who maintains it, what it will and will not do, and how it is funded.

Sebastien Rousseau https://askiso.io/conformance/

AskISO agrees with libxml2 on all 4,746 documents tested. Every figure here names the command that reproduces it, so you can check the claim yourself.

Sebastien Rousseau https://askiso.io/contact/

Reach the people behind AskISO. Report a message it gets wrong, ask about November 2026 readiness, or request the release notes. Replies come by email.

Sebastien Rousseau https://askiso.io/contact/sent/

Confirmation that your message reached AskISO, what happens to it next, and where to go while you wait for a reply.

Sebastien Rousseau https://askiso.io/deadline/

CBPR+ will reject unstructured postal addresses. Swift deferred the November cutover and confirms new timing by December. Check your own messages free.

Sebastien Rousseau https://askiso.io/docs/

Every AskISO command, which ones need a catalogue, the scheme rule profiles, and how to wire it into your editor, your build or an AI assistant.

Sebastien Rousseau https://askiso.io/innovation/

The message families AskISO covers today, what is being built next, and the constraints that decide what gets built at all.

Sebastien Rousseau https://askiso.io/knowledge/

Everything AskISO publishes about ISO 20022 in one place: the CBPR+ SR2025 message guidance, 2026 readiness rules, documentation and evidence.

Sebastien Rousseau https://askiso.io/legal/

What AskISO collects, what it does not, the licence it is published under, and its relationship to ISO and SWIFT. No analytics, no cookies, no accounts.

Sebastien Rousseau https://askiso.io/mcp/

Thirteen open MCP servers that turn plain language into validated ISO 20022 messages: initiate, settle, read, reconcile, remediate, prove readiness.

Sebastien Rousseau https://askiso.io/mcp/recipes/

Four flows an agent runs end to end: migrate an MT103, reconcile a statement, recall a wrong payment, and turn a signed agent mandate into a wire.

Sebastien Rousseau https://askiso.io/mcp/setup/

Add the ISO 20022 MCP servers to Claude Code, Claude Desktop or any MCP client in one step, then make your first validated message from a prompt.
