Keynote: After the Tool Call: What MCP Leaves Open and How to Close It - Viren Baraiya, CTO, Orkes and Co-Creator of Netflix Conductor

Friday August 14, 2026 10:15 - 10:30 KST

Grand Ballroom 1 + 2

Every team building production agents is solving the same execution problems independently: what happens when a tool call runs for an hour, when the process crashes mid-sequence, when a downstream failure requires earlier steps to be undone. MCP doesn't specify this — deliberately. But the absence of shared patterns is costing the ecosystem duplicated effort and incompatible implementations.

This talk contributes a named, reusable pattern — MCP tool sequences as durable sagas with compensation semantics — and puts three concrete candidates on the table for spec extension: async tool results, execution receipts, and cancellation propagation semantics. A worked implementation serves as existence proof that all three are tractable today, not theoretical.

It also reframes how MCP fits into agent architecture: as the intent layer within a larger execution model, not the execution model itself. That distinction makes MCP more composable and keeps the spec lean as the ecosystem scales.
