01
OpenAI notified SpaceX it will wind down the Cursor contract, proposed shutoff Nov 12, because it cannot be confident SpaceX will use the technology within its terms. First-party note, not a feature recap. That is the change-of-control enforcement, not a model launch.
02
The 611-point thread is the street read. rgbrenner: this was bound to happen once Cursor decided to sell itself to a competing model provider. The comments are the argument; the OpenAI page is the document.

The CEO line circulating this window: OpenAI models are about 5% of Cursor user traffic. r/cursor is already asking whether Anthropic follows. A share-of-traffic claim, not a shutdown of the product.

Entries still open through Sep 3. ChatGPT's desktop in-app browser now consumes site tools; GitHub notes Shopify flipped WebMCP on for Liquid storefronts. The contest is live. Whether sites publish tools is still unproved.

Small, sharp thread. bikeshaving: if you care about web standards, do not participate. He calls document.modelContext a staple of a global RPC registry with structured JSON payloads onto the DOM. The challenge is a hackathon and a standards fight.
06
First-party: ChatGPT desktop's built-in browser consumes WebMCP. Distribution for the challenge, not a duplicate of the contest page.

First-party Aug 25: orchestrator, planner, and tool router on an NVIDIA DGX Spark with Qwen 3.8 27B or PPLX 27B. Local steps burn no credits; cloud hops need permission. HN is unconvinced the buyer exists. Local-first still means an expensive NVIDIA box plus a Pro/Max login.
