Amazon grants Claude direct access to seller data and tools after blocking Muse

Amazon announced Wednesday that U.S. sellers can connect their Selling Partner accounts directly to Claude, Anthropic's AI assistant, enabling the tool to access catalogs, real-time performance metrics, inventory data and pricing recommendations. The move represents Amazon's clearer policy on outside AI agents: approved tools can link through Amazon-built connections, while unauthorized agents attempting to access the retail site face being shut out, as happened to Meta's Muse earlier this week. Amazon has invested $13 billion in Anthropic with potential for another $20 billion tied to commercial milestones, while Anthropic has committed to spending over $100 billion on AWS technologies over the next decade. The announcements show Amazon drawing a strategic line on AI agents, allowing preferred partners approved access while blocking competitors.
