Separately, a tweet from Nick Baumann indicates ChatGPT Work on the web ships with its own built-in browser plus other unspecified primitives. OpenAI is running a hackathon to encourage developers to build on the new WebMCP support, though a wider rollout timeline beyond the hackathon hasn't been announced. ## Content OpenAI has added WebMCP support to the ChatGPT desktop in-app browser, along with a hackathon to encourage developers to build on top of it. WebMCP is worth understanding on its own terms, because it's genuinely different from regular MCPs or APIs. Instead of exposing functionality through a server endpoint, WebMCP is exposed directly through the browser. That makes it useful for situations where you want an agent and a human working together on the same UI - think co-editing notebook cells rather than handing off a task entirely to automation. To show what this looks like in practice, OpenAI published a blog post (authored by Jeremy Lewi) demonstrating a new kind of notebook built around WebMCP. The notebook is designed around a specific philosophy: meet people where they are. Files are just markdown, you bring your own coding agent, and the whole thing is open source. Lewi uses it to curate runbooks and high-quality examples for running foundation model evals on their infrastructure - the kind of work that benefits from interactive tinkering with long-running jobs while keeping notes inline. On the ChatGPT side more broadly, the work-focused web version now ships with its own browser, among other primitives aimed at agentic workflows. Developer-facing updates also landed for plugins and Codex integrations around the same time, with a dedicated WebMCP site going up to support builders getting started. ## Questions this post answers ### What is WebMCP support in ChatGPT's browser? WebMCP is a protocol that lets ChatGPT's built-in desktop browser talk directly to web pages in a standardized way, rather than just clicking and scraping visually. OpenAI's James Sun confirmed the ChatGPT desktop in-app browser now supports it, and OpenAI is running a hackathon to get developers building on top of the feature before a wider rollout. _Developers experimenting with agentic browsing and WebMCP can track early rollout details on daily.dev._ --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#openai](https://daily.dev/tags/openai), [#chatgpt](https://daily.dev/tags/chatgpt), [#mcp](https://daily.dev/tags/mcp) [View this post on daily.dev](https://daily.dev/posts/chatgpt-s-web-browser-gets-webmcp-support-and-new-primitives-hnhtsdeii) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"ChatGPT's Web Browser Gets WebMCP Support and New Primitives","url":"https://daily.dev/posts/chatgpt-s-web-browser-gets-webmcp-support-and-new-primitives-hnhtsdeii","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/chatgpt-s-web-browser-gets-webmcp-support-and-new-primitives-hnhtsdeii"},"datePublished":"2026-08-26T04:21:45.934Z","dateModified":"2026-08-27T21:31:15.572Z","description":"ChatGPT's desktop in-app browser now supports WebMCP, a protocol that lets AI agents interact directly with web pages through standardized calls, according to...","isAccessibleForFree":true,"articleSection":"Collections","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collections","logo":"https://media.daily.dev/image/upload/s--fk_6ycEi--/f_auto,q_auto/v1780996001/logos/collections?_a=BAMAMiWQ0","url":"https://daily.dev/sources/collections"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/chatgpt-s-web-browser-gets-webmcp-support-and-new-primitives-hnhtsdeii","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents,openai,chatgpt,mcp","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collections","item":"https://daily.dev/sources/collections"},{"@type":"ListItem","position":3,"name":"ChatGPT's Web Browser Gets WebMCP Support and New Primitives"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/chatgpt-s-web-browser-gets-webmcp-support-and-new-primitives-hnhtsdeii#faq","mainEntity":[{"@type":"Question","name":"What is WebMCP support in ChatGPT's browser?","acceptedAnswer":{"@type":"Answer","text":"WebMCP is a protocol that lets ChatGPT's built-in desktop browser talk directly to web pages in a standardized way, rather than just clicking and scraping visually.
