Using MCP without any LLM: deterministic cloud cost estimation pipeline

whispered_word12 · reddit · 2026-10-15

A CloudKeeper team built a cloud migration cost estimation pipeline using three MCP servers and Python — with no LLM or AI agent in the loop. MCP handled tool interaction while the estimation stayed fully deterministic: defined inputs, tool calls, calculations. The author suggests MCP could be useful as a general tool-interaction protocol for regular backend services and automation, not just AI apps, and asks for other non-AI use cases.
