Arcade brings secure MCP actions to Antigravity

The sharp part of Arcade’s pitch is that it sells the missing production layer for agents: auth, delegated access, and reliable execution.

• –User-scoped OAuth matters more than model cleverness when an agent needs to send mail, update docs, or schedule meetings.
• –MCP gives the interface, but the runtime is the part teams struggle to build once security review and multi-user access show up.
• –The Google Workspace plus Slack surface area shows this is aimed at real operational automation, not toy copilots.
• –Arcade’s open-source and Product Hunt positioning fits an infrastructure company that wins on trust and adoption, not just demo flair.
