Schema changes break downstream code without notice

7/10 High

When API providers deprecate fields (e.g., replacing `name` with `first_name` and `last_name`), dependent code breaks immediately. Developers must update SDKs, fix code, test, and redeploy—a reactive cycle that causes unplanned downtime and rework.

Query: “What are the most common pain points with MCP for developers in 2025?4/7/2026

the API provider (hopefully unintentionally) updates their schema. The `name` field is deprecated in favor of separate `first_name` and `last_name` fields. Your code breaks.
