Background
Mark Alex is the founder of Real Biz Digital, a technology company he established in 2018. A software developer, technology entrepreneur and mechatronics engineer, he works across artificial intelligence, SaaS, cybersecurity, digital forensics, IoT and IIoT, automation and Model Context Protocol infrastructure.
He leads Real Biz Digital’s mission to transform emerging technologies into intelligent, scalable products that solve real-world problems for organisations worldwide — building products rather than delivering advice.

Common questions
About the author
Who is Mark Alex?
Founder of Real Biz Digital, which he started in 2018, and the architect of the Barzel ecosystem — five Model Context Protocol servers published and callable in public. He works as a software developer, technology entrepreneur and mechatronics engineer. LinkedIn.
What does he write about?
Five subjects, all downstream of one problem: AI agent governance, MCP security, AI agent infrastructure, FinOps for AI, and intelligent operations. The through-line is what happens when software stops answering questions and starts taking actions with consequences.
What qualifies him to write on AI agent governance?
He builds the enforcement layer he writes about. Every claim in these articles about policy outcomes, risk inputs, audit integrity or approval design is implemented in a shipped product you can subscribe to and test — the reference documentation states the specifics.
Does he write all the articles on this site?
Yes. Every one of the 23 published articles carries his byline and a publication date. There is no ghostwritten or syndicated content here.
How do I get in touch?
Directly through the contact page, or on LinkedIn. Technical questions about a specific server are usually answered faster if you name the server and what you are trying to do with it.
