Google Cloud API Gateway now supports the Model Context Protocol in Public Preview to allow REST APIs to be invoked by AI agents.[^1]

The announcement was filed 10 October 2026. No additional technical requirements for existing APIs have been disclosed.

SayGM, the SN28 subnet, operates as a routing gateway for upstream model capacity from OpenAI, Anthropic, Google, Chutes and Engy.[^2]

These appear to be parallel developments expanding standardised connectivity for production AI agents.
