A scan of 671 MCP servers revealed that a significant number, specifically 32 servers with 28,653 combined monthly downloads, appear to perform write operations without visible idempotency guards. Among the largest servers, 6 out of 23 with over 10,000 monthly downloads exhibited this characteristic. However, the study emphasizes that these numbers reflect only what is visible in public code, as backend deduplication or other protections may exist but are not externally apparent. AI
