- An agent differs from a chatbot in that it plans, uses tools and carries out several steps on its own.
- MCP is an open standard through which AI systems access tools and data in a controlled way, comparable to a USB port for AI.
- What is realistic today are clearly scoped tasks under supervision, not a digital employee who does everything alone.
Affects you if you have recurring workflows that today mean click-work between several systems.
01Chatbot or agent: the difference
A chatbot receives a question and gives an answer, and that ends the round. An agent receives a goal: it breaks it into steps, calls tools, looks at intermediate results and corrects course until the task is done. The difference is not intelligence but access to tools and the ability to take several steps in a row.
02What MCP is
For an agent to work with your shop, your inventory system or your calendar, it needs a connection to them. The Model Context Protocol, MCP for short, is an open standard for exactly that: a common language through which AI systems talk to tools and data sources. Often described as a USB port for AI: one plug, many devices.
The advantage for you: a connection built once as an MCP server works with different AI tools. You are not tied to a single vendor.
03Realistic examples in a small business
- Looking up order status: a customer request comes in, the agent fetches the order and shipping history from the shop system and prepares a ready draft reply.
- Compiling reports: every Monday, pulling numbers from shop and accounting and filing them as a readable summary.
- Moving data between systems: transferring new products from inventory to the shop, including a formatted description.
- Pre-sorting invoices: reading incoming receipts, matching them and presenting them for approval.
04Where the limits are
- Supervision: agents make mistakes, and confidently so. Critical steps like sending, booking or deleting belong behind a human approval.
- Permissions: an agent should only have the access its task requires. No full access, anywhere.
- Failure cases: what happens with a half-finished task? That question needs an answer up front, not at the first incident.
- Economics: an agent for a workflow that happens twice a month rarely pays off.
05A sober look
The honest state of things: agents work well today for clearly scoped, recurring tasks with defined tools and a human who approves results. They replace neither skilled staff nor proper process design. Start small, automate one workflow cleanly and build in approvals: a year from now you have a tool that saves time every day instead of a construction site.
Start with read access: looking things up, summarising, pre-sorting. Writing steps come later, once trust has grown through experience.
- Pick one workflow that happens often and today means click-work between two systems.
- Check whether your tools already offer MCP connections or other interfaces.
- Start with reading tasks: looking up, summarising, pre-sorting.
- Define approvals: which steps the agent may take alone and which only with your sign-off.
- Review the results rigorously in the first weeks and refine the workflow.
