• –MCP gives agent builders a sanctioned integration path instead of fragile browser automation.
• –Spending limits, transaction approvals, limited data access, and revocation address the biggest consumer risks.
• –Walmart gains a shot at owning agent-driven commerce before outside assistants become the default discovery layer.
• –Developers will need structured, current inventory and pricing data for agents to make dependable recommendations.
• –Adoption remains uncertain: only 16% of shoppers currently feel comfortable letting AI purchase on their behalf, according to [Axios](https://www.axios.com/2026/10/21/walmart-amazon-agents-muse).
