Pillar: Spicy take + Builder how-to (cross-rotation after Run 7's capability pillar). Brings the funding/capability arc back to the protocol layer.
Hook
Google just adopted Anthropic's protocol as its default.
Gemini Spark MCP support launches this week. US AI Ultra subscribers get it tomorrow.
This is the moment AI plugins die and AI tools win.
Key anchors
- Spark MCP rollout: week of 2026-05-26 to US AI Ultra subscribers (first wave: Canva, OpenTable, Instacart; summer: Notion, GitHub, Slack)
- Google did not build a proprietary plugin store. It picked MCP (Anthropic's open standard)
- One MCP server now serves Claude, Spark, and every agent runtime that adopts the protocol
- 2026 SaaS roadmap question shifted from "how do we add AI" to "how do we become the tool an agent reaches for"
3-move builder framework
- Ship an MCP server. Even thin (auth, common actions, basic search).
- Design for partial autonomy. Best agent UX is "I drafted this, approve?".
- Pick the one workflow where your tool is the first port of call. Make that the demo.
