In my previous article on preparing CI/CD pipelines to ship production-ready agents, I argued that we cannot ship agents to production that are driven primarily by non-deterministic models. Instead, they must be built as robust workflows where the large language model (LLM) is introduced strategically at specific steps within a deterministic control flow.
Now we must examine the most critical node in that framework.
The Model Context Protocol (MCP) server facilitates interactions between the probabilistic LLM node and the deterministic…
