v0 adds MCP server tools, Excel/Word file attachments, and Platform API v2 beta

What's new

• v0 MCP server: New MCP tools for AI agents — create, find and read chats, fetch previews, send messages
• Excel and Word attachments: Attach .xlsx and .docx files to v0 chat — appear as inline chips in the prompt
• Platform API v2 (beta): Start a chat from a GitHub repository with migration guides
• Faster VM startup: Several seconds saved on sandbox and Vercel deployment startup
• Higher sandbox limit: Unauthenticated users get higher preview limit of 240/hr

Why it matters

The MCP server opens v0 to AI agents — developer agents can now programmatically create and read v0 chats. Excel/Word support appeals to enterprise users working with spreadsheets and documentation.

How to try it

v0 MCP server available in v0.dev settings. Platform API v2 beta at v0.app/changelog.
