Merge's eval claims its MCP connectors beat Microsoft's native servers on tool count and reliability
shensi · x · 2026-11-05
Merge published a head-to-head eval of its MCP connectors versus Microsoft's official servers for Outlook, OneDrive and SharePoint:
- Tool coverage: Merge exposed 128 tools across the three products vs 96 on Microsoft's servers (Outlook 53 vs 38, OneDrive 41 vs 22, SharePoint 34 vs 36).
- Reliability: Each task ran 15 times per server. Merge hit tool errors in 40 runs total vs 70 for Microsoft; OneDrive saw zero errors on Merge vs 8; Outlook 25 vs 47 (47% fewer); SharePoint tied at 15.
The takeaway: Merge's unified connector layer offers more tools and fewer failures than Microsoft's native MCP, except a slight SharePoint tool-count gap. Vendor-run eval, so treat with some caution, but the data is granular.
