Unlike enterprise APIs designed for deterministic software callers, MCP serves autonomous AI agents, which demands different interface design principles: high-intent single-call interfaces instead of nested resource hierarchies, structured error responses that enable agent self-correction, and scoped OAuth 2.0 tokens per agent session for fine-grained auth and audit trails. Response sanitization matters because verbose outputs increase LLM hallucination risk. Latency SLOs from enterprise APIs should carry over, but logging must capture session-level reasoning chains rather than isolated requests. Capacity planning is harder because agent-driven traffic is bursty and unpredictable — fan-out from a single prompt can spike load instantly — so load testing should simulate abrupt surges rather than gradual ramp-ups. ## Full article daily.dev links to this article rather than hosting it.
