Why I chose MCP over RAG for live infrastructure auditing
The article discusses the author's decision to use MCP instead of RAG for auditing distributed hardware infrastructure. The author explains that RAG was initially chosen but proved inadequate due to its reliance on outdated data snapshots. By switching to a database query approach, the author was able to access real-time device states and improve compliance auditing.
- ▪The author initially chose RAG for its ability to reason over embedded documents but switched to MCP after realizing RAG's limitations with stale data.
- ▪MCP allows for real-time access to device states, which is crucial for compliance auditing.
- ▪A FastAPI gateway was implemented to manage queries and enforce rate limits, saving costs during development.
