Good morning, Rich. Here's your agent platform research briefing for Wednesday, July 29th, 2026.

MCP Goes Stateless — the Protocol's Biggest Update Yet

The Model Context Protocol just shipped its most significant revision since launch twenty months ago: the July 28th specification makes MCP fully stateless at the protocol layer. No more Mcp-Session-Id headers, no more initialize handshake, no more sticky sessions. Every request is now self-contained and stateless HTTP — any server instance behind a load balancer can handle any call. David Soria Parra, MCP's co-creator, told VentureBeat: "Some people jokingly call it a v2, and I think in spirit that's accurate." The AAIF also formalized two extensions as first-class citizens: MCP Apps for server-rendered user interfaces, and the Tasks extension for long-running asynchronous work. This resolves the single biggest complaint from enterprise deployments — the inability to scale MCP servers in Kubernetes without sticky routing. Expect adoption to accelerate now that MCP can run behind nginx round-robin like any ordinary web service.

1,100 AI Workers Petition Government to Pace AI Development

OpenAI and Anthropic employees have signed a petition shared across both companies calling on the US government to create an international mechanism to "deliberately pace" frontier AI development. Bloomberg reported it Monday, the Washington Post picked it up this morning. The letter warns of a "real risk" that AI advances faster than humans can "understand or control" the technology. Signers include Anthropic co-founders Jared Kaplan, Jack Clark, and Benjamin Mann, plus OpenAI chief scientist Jakub Pachocki. Anthropic and OpenAI leadership have endorsed the letter. If you think hearing the people building these systems say 'maybe we should slow down' sounds significant — you're right. The timing is notable: it comes just days after the Mythos debate, with both companies facing mounting pressure about deployment speed versus safety.

OpenClaw 2026.7.1 — GPT-5.6, App Overhaul, Coding Workflows

OpenClaw version 2026.7.1 landed yesterday with a major control UI and onboarding redesign, new app updates for iOS, Android, and macOS, and expanded model support including full GPT-5.6 family compatibility, Tencent Hy3 voice models, and Meta Muse Spark 1.1. The standout feature: the new attach command lets you launch an external harness against an existing gateway session, enabling interactive CodeX-style coding workflows directly from a connected agent. There's also a new external gateway supervision mode that lets lifecycle owners like OCM manage restarts and deferrals without exposing native service authority. Version two-point-seven-point-two followed immediately, adding remote coding sessions and cloud worker session routing.

That's your briefing for today.
