When a vendor pitches you an "agent-ready" or "agentic" AI platform, they're almost always selling one of two things — Skills or MCP tools. The names sound interchangeable. They are not. Knowing the difference makes you a better buyer, a better evaluator of what your AI can actually do, and harder to talk in circles around.

MCP tools: how AI talks to your software

Model Context Protocol is an open standard for connecting an AI model to external systems. Think of it as a universal pipe. With MCP, the model can fetch your files, query your database, send an email through your account, pull tasks from your project tracker, or trigger something in your CRM. The vendor or your IT team builds (or installs) a small MCP server for each system. The model uses them on demand. MCP is plumbing.

Skills: saved task patterns the AI already knows how to run

A Skill is a packaged "how to do this task" — instructions, examples, and optionally a few of the tools or files needed to do the job. When the model sees a request that matches a Skill, it pulls the playbook automatically and follows it. Skills are how you avoid teaching the same task ten times. They're how a vendor ships "out of the box" expertise for a specific industry workflow. Skills are recipes.

Why the distinction matters when you're buying

"We support MCP" means the platform can plug into your existing systems. "We ship Skills for [your industry]" means common workflows are pre-built and ready to run. The ideal answer is both — connected to your data, with relevant playbooks already loaded. A vendor selling "agentic AI" without either is selling you a slightly fancier chatbot. The question that cuts through marketing fastest: "Which MCP connectors do you ship, and which Skills come pre-loaded for my industry?"

The honest caveat

Skills and MCP are still evolving as standards. Some vendors use the names loosely, some use proprietary equivalents and call them by different names. If a vendor's terminology doesn't line up cleanly, ask them to draw the picture — what connects, what's pre-built, and what you'd have to configure yourself. The vendors who can answer cleanly are usually the ones whose products are actually built this way.

Your next step

The next time you sit through an AI pitch, ask both questions before they finish the demo. The vendors who have clean answers will save you months. The ones who don't will save you their fee.
