MCP registry triples in size, but latest spec adoption stalls

By PulseAugur Editorial · [1 sources] ·

The MCP registry has experienced a significant surge in registrations, tripling in size over a two-week period to over 150,000 name:version pairs. Despite this rapid growth, an analysis of 300 newly registered names revealed that the adoption rate of the latest MCP specification (2026-07-28 era) has not increased, remaining around 22.3%.
