FAQ from Buildy
What client endpoints does Buildy support?
The endpoint https://app.buildy.so/mcp works with Claude, Grok, Gemini, and Perplexity. ChatGPT users connect via https://app.buildy.so/mcp/chatgpt or the Buildy listing in the ChatGPT Apps directory.
How do I start building an app with Buildy?
Once connected, paste the starter prompt provided in the README. It asks you to suggest apps based on what the AI knows about you or poses short questions to find an idea, then helps create the first app.
Can I use Buildy with coding agents like Codex or Cursor?
Yes. Install the Buildy authoring skill from skills.sh (npx skills add tambo-labs/buildy-mcp). Codex users can install the bundled Buildy Codex plugin. The skill teaches the agent Buildy’s build contract and workflow.
What authentication does Buildy require?
OAuth with Dynamic Client Registration is automatic for clients that support it, showing a one-time consent screen. No manual token setup is needed.
Can I make an app private again after making it public?
Yes. Use the unset_public tool to make a public app private. Anonymous visitors can no longer open it.
