Each MCP interaction may stuff a large amount of tool metadata and historical context into the prompt, causing token consumption to rise rapidly, driving up costs and crowding out effective reasoning space.

UnverifiedHidden cost sources of token overhead include overly long system prompts, redundant context information, inefficient prompt engineering, and repeated codebase indexing.69% similarUnverifiedAlthough MCP Resources are read-only, they may dump hundreds of sensitive records into the model context at once, making them an easily overlooked data-leak surface; resources should be subject to the same permission checks and size limits as tools.68% similarUnverifiedInference serving cost scales with query volume and is predictable and elastically scalable; re-embedding cost scales with the total historical data volume and only increases, and for a warehouse holding years of data, the backfill cost may far exceed the ongoing inference bill.68% similarUnverifiedThe advantage of RAG architecture is that new knowledge can be injected without retraining the model, but the trade-off is that prompt length (number of input tokens) grows significantly as retrieved content increases.68% similarVerifiedThe larger the context window, the more information the model can remember in a single call, but it also brings rising inference costs and the problem of intermediate information being ignored.67% similar
