Notes on development, AI integration, and the things we build.

    Written authorization for pentest under KZ-1 Art. 221 — why paper outranks tools

    A pentest without written authorization is a criminal offense under KZ-1 Art. 221. The nine clauses that NIST SP 800-115 and PTES treat as baseline, the single most-violated pitfall on Slovenian hosting and CMS platforms, and a PDF template with all GDPR Art. 28 clauses.

    Pitfalls of introducing AI agents into a business — and how to avoid them

    AI agents work, but most failures are predictable. An honest review of the pitfalls in quoting, design and operations — and what separates an expensive demo from a tool that actually saves time.

    Case study: how we'd build an AI agent for quotes

    A reference implementation for a make-to-order business: Claude Desktop describes a job, an MCP server computes the price deterministically and returns a PDF quote. Architecture, pricing model, tools and an example flow.

  4. A quote document and a price list as the calculation tool
    AI & automation

    How to generate quotes with an AI agent — and why the model must not price them

    An increasingly common wish: “I want to describe a job in Claude Desktop and get a quote.” It's doable — but only if a tool computes the price, not the language model. Here's how.

  5. A browser and an AI agent calling the page's tools
    Websites

    AI-ready websites: why your site will need to talk to agents

    AI agents increasingly browse the web instead of people. We explain what an “AI-ready” site means — structured data, llms.txt and WebMCP — and why it's becoming a search and competitive lever.

    AI & automation

    MCP connectors: how to connect Claude or ChatGPT to your own tools

    An AI assistant becomes useful only when it can see your data and take actions. We show what an MCP connector is, what it enables, and how to set it up safely.

    The robot as a colleague: what automation really means for a small business

    “The robot is no longer the future – it's a colleague” was the title of the round table in Ptuj. What that means in practice for a craftsperson or small business — and where it's worth starting.

    The robot is no longer the future, it's a colleague — round table, Ptuj

    We attended the round table “The robot is no longer the future – it's a colleague” at Dan obrti in podjetništva 2026 in Ptuj — automation, AI and a humanoid plus quadruped robot demonstration.

    Updates

    We embedded a WebMCP server: AI agents can now talk to racunalnicar.eu

    We equipped racunalnicar.eu with a WebMCP server — AI agents can read services and products, fetch contact details and submit an inquiry over the MCP protocol. Here is how it works.
