Questions
Do I need API keys?
No. You sign in with your account. Claude and the other tools never see your credentials.
Which assistants work?
Claude on the web, desktop, mobile and Claude Code. Also ChatGPT, Gemini CLI, Cursor, VS Code, Windsurf and any MCP client.
Can the AI change things without asking?
Only inside your limits. Turn on approvals for sensitive changes, preview every change, and undo from the log.
How is this different from Amazon's Ads MCP server?
Amazon's is for Ads API partners with their own API credentials. Build needs only an account. It adds sales, inventory and Vendor Central data, writes with guardrails, and more marketplaces as they launch. You can run both.
What does it cost?
The MCP server is included on every plan, including Free. See pricing.
Is it the same as SellerMate's MCP server?
Yes. Build and SellerMate share accounts and one MCP server.
