Notes from the field on marketplaces, ecommerce integrations, data feeds and AI automation, byJabane Mohamed Ayoub.
Convert JSON to XML in n8n with the Data Mapper node: write attributes, repeated elements, lookups and formatted dates into a real XML invoice, no Code node.
A practical pattern for connecting an agent to four different systems: one shared connector interface, so search and citations don't special-case each source.
A business requirement describes an outcome. A spec describes a mechanism. The gap between them is where most integration ambiguity actually hides.
A practical MCP security model: scope permissions per caller, keep secrets out of the model's context entirely, and never let a tool exceed its agent's access.
Message Template is an open-source n8n node that renders text, JSON, XML or a file from an expression template, per item or combined across all items.
Preventing unsafe AI agent actions is an architecture problem, not a prompting one: four concrete layers that actually stop damage before it happens.
Data Mapper is an open-source n8n node that maps incoming data onto a target profile by drag and drop and outputs XML, JSON or CSV, no Code node needed.
Practical rules for designing MCP tools that an agent can actually use well: narrow scope, task-shaped names, bounded results, and no mode flags.
Why fine-tuning is the wrong tool for knowledge that changes weekly, and when it's actually the right one: a practical comparison for business teams.
A discovery workshop fails for one of two reasons: nobody in the room can answer the question, or everyone answers a different one. Fix both.
Why the next wave of AI automation is many narrow, domain-specific agents instead of one general-purpose agent, and how to start building that way.
Six lessons from building Nexus's citation system: why similar text isn't trustworthy evidence, and what actually makes a RAG answer verifiable.
