Arcade ToolBench Indexes 41,902 MCP Servers — Only 0.5% Earn A Grade Across Quality, Security, and Compliance

Arcade / ToolBench·medium signal

Arcade's ToolBench benchmark now indexes 41,902 MCP servers graded across definition quality, protocol compliance, security, and supportability — and only 0.5% earn an A or above. The benchmark provides the first systematic quality assessment of the MCP ecosystem at scale. Separately, Arcade shipped 5 new production-grade MCP servers for Microsoft Office 365 (Word, Excel, PowerPoint, OneDrive, SharePoint) with OAuth, binary format handling, and concurrent edit support.
