Chat - Still in preview #1413

Chat got a major upgrade this week. Streaming responses now support interactive tool-approval flows, so you can review and approve each tool call as it happens. A new multi-provider model picker lets you choose between providers and models. Agent and tool calls render as expandable UI blocks with tool-specific displays, and a new web search tool lets Claude fetch and reference live content.

We also shipped a series of fixes to MCP connectivity — replacing the stagnant mcp-handler library with a direct SDK transport #1518, fixing OAuth connections through the reverse proxy #1512, and resolving SDK version conflicts that caused session failures #1515 #1516.

Chat with tool approval
