Anthropic launches the MCP Apps open spec, in Claude.ai

**Anthropic** has officially absorbed the independent MCP UI project and, collaborating with **OpenAI**, **Block**, **VS Code**, **Antigravity**, **JetBrains**, and **AWS**, released the **MCP Apps spec** and official support in **Claude.ai**. This standard aims to enable a rich ecosystem of interoperable applications with rich UI, addressing the proliferation of subscription services. Meanwhile, **NVIDIA** introduced **ToolOrchestra** with an **8B orchestrator** model trained via scalable reinforcement learning for efficient agent orchestration. The concept of Recursive Language Models (RLMs) is gaining traction for efficient context management in agent stacks. The “Clawdbot” UX pattern emphasizes outcome-first assistant design with tight context and tool integration, sparking security concerns around prompt injection. **Alibaba** launched **Qwen3-Max-Thinking**, a flagship reasoning and agent model with adaptive tool use and strong benchmark scores, now available in public evaluation platforms like LM Arena and Yupp.
