Connect the MCP in Codex
Available nowYou need the Codex app and a signed-in account with access to MCP settings. No separate See Then Build login or model API key is required for these public tools.
- Open Codex settings.
Go to Settings → MCP servers, then choose Add server.
- Name the connection.
Enter
see-then-buildand choose Streamable HTTP. - Paste the server URL.
The public connection does not require authentication. Leave API keys and authorization headers empty.
https://seethenbuild.com/api/mcp - Save and restart Codex.
Choose Save, then Restart. Start a new task so it picks up the connection.
- Try your first request.
Use See Then Build to show me the latest daily demos. Include each demo’s creator and its See Then Build page link.
You should receive a dated edition with demo links. If a new edition is unavailable, ask for the latest published edition.
This connects the public tools; it does not install the packaged plugin workflows. Inline cards, imported workflows, and available creation tools depend on your chat app. In a managed workspace, your administrator may restrict MCP connections.
