NVIDIA GTC, The Death of MCP, and AI Agents Are Hiring Humans - This Week in AI
from Agents Hour · host Mastra
Shane hosts this week's news from his usual studio while Abhi joins remotely from NVIDIA GTC 2026 in San Jose. Jensen Huang's keynote set the tone: NVIDIA is doubling down on AI factories, pushing 100x more token throughput, and helping bring OpenAI onto AWS infrastructure. RentAHuman is a startup that lets AI agents hire humans for physical tasks they can't do themselves. Perplexity's CTO said internally they're moving away from MCPs toward APIs and CLIs, but Chrome 146 shipping native MCP support may have undercut that argument immediately. Anthropic had a strong week: 1M context window is now GA for Opus 4.6 and Sonnet 4.6 with no beta header required, Opus 4.6 1M is now the default model for Claude Code on Max/Team/Enterprise with no long context price premium, and the new /btw command lets you have side conversations while Claude is working. Vercel and Cloudflare reignited their ongoing drama over the just-bash fork. Ramp launched credit cards for agents and Perplexity announced Personal Computer, an always-on local agent running on a Mac mini. Developer stack coverage includes Resend's open-source CLI with 53 commands, pnpm 11's git worktrees support for multi-agent monorepos, and OpenAI pushing a full computer environment behind the Responses API. Deeper reads from Sunil Pai on generative UI post-WIMP interfaces, Elliot Arledge on the RL environment business, and Jay Scambler's Autocontext harness. Quick hits: Replit Agent 4, Manus Desktop, NemoClaw from NVIDIA, llmock by CopilotKit, ContextKing raising to kill vector DBs, Google Maps getting Gemini, and Z.ai's GLM-5-Turbo optimized for Claude Code. AI Agents Hour is a weekly livestream hosted by Mastra CPO Shane Thomas and CTO Abhi Aiyer. Airing Mondays at 12PM Pacific on YouTube and X. 📚 READ MORE RentAHuman https://x.com/polymarket/status/2032470045217939723 Perplexity CTO moving away from MCPs https://x.com/morganlinton/status/2031795683897077965 Chrome 146 native MCP support https://x.com/xpasky/status/2032252486145253865 Claude 1M context window GA https://x.com/claudeai/status/2032509548297343196 Opus 4.6 1M default for Claude Code https://x.com/alexalbert__/status/2032522722551689363 Claude Code /btw command https://x.com/trq212/status/2031506296697131352 Vercel CTO on just-bash fork https://x.com/cramforce/status/2033285112478171373 Guillermo Rauch on Cloudflare https://x.com/rauchg/status/2033291143715455458 Ramp Agent Cards https://x.com/i/trending/2031832827063648342 Perplexity Personal Computer https://x.com/perplexity_ai/status/2031790180521427166 Resend CLI https://x.com/zenorocha/status/2032459310341800314 pnpm 11 git worktrees https://pnpm.io/11.x/git-worktrees OpenAI Responses API computer environment https://openai.com/index/equip-responses-api-computer-environment/ Sunil Pai — After WIMP https://sunilpai.dev/posts/after-wimp/ Elliot Arledge — The RL Environment Business https://x.com/elliotarledge/status/2032753593535574433 Autocontext — Jay Scambler https://x.com/JayScambler/status/2032508829959868690 Kimi Attention Residuals https://x.com/Kimi_Moonshot/status/2033378587878072424 Replit Agent 4 https://x.com/amasad/status/2031755113694679094 Manus Desktop https://x.com/ManusAI/status/2033558672152854712 NemoClaw — NVIDIA https://nemoclaw.so llmock by CopilotKit https://llmock.copilotkit.dev ContextKing — killing vector DBs https://x.com/contextkingceo/status/2032098309029220456 Google Maps biggest upgrade https://x.com/google/status/2032079594191261938 Z.ai GLM-5-Turbo https://x.com/Zai_org/status/2033221428640674015 📚 MASTRA RESOURCES Mastra: https://mastra.ai Mastra on X: https://x.com/mastra_ai Mastra Discord: https://mastra.ai/community/discord Mastra GitHub: https://github.com/mastra-ai Learn Mastra in the world's first MCP-Based Course: https://mastra.ai/course Principles of Building AI Agents (Book): https://mastra.ai/books/principles-of-building-ai-agents Patterns for Building AI Agents (New Book): https://mastra.ai/books/patterns-of-building-ai-agents MASTRA? Mastra is an open-source TypeScript framework designed for building and shipping AI-powered applications and agents with minimal friction. It supports the full lifecycle of agent development—from prototype to production. You can integrate it with frontend and backend stacks (e.g., React, Next.js, Node) or run agents as standalone services. If you’re a JavaScript or TypeScript developer looking to build an agentic or AI-powered product without starting from first principles, Mastra provides the scaffolding, tools, and integrations to accelerate that process. 00:00 — NVIDIA GTC 2026 04:16 — RentAHuman 07:56 — Is MCP dead? 13:08 — Anthropic ships 14:59 — Vercel vs Cloudflare: the just-bash fork drama 18:59 — Ramp Agent Cards & Perplexity Personal Computer 20:52 — Resend CLI, pnpm worktrees, OpenAI Responses API 23:04 — Developer insights
