## Summary

You can turn a PDF into an audiobook by linking your existing OpenAI subscription to a PDF‑to‑MP3 MCP server. In Codex, open Settings → Plugins → Add MCP server, select Streamable HTTP, paste the server address, then authenticate. After connecting, add a speech API key that pays only for the speech portion.

Attach a PDF in your AI chat and ask the MCP to create an audiobook. The document‑processing step uses the credits already covered by your subscription, while the speech generation is billed by Google or OpenAI according to their usage rates. The guide also offers a direct “Use my API key” option for those who prefer to supply their own speech credentials.

The workflow lets marketers, founders, and content creators produce narrated content without extra subscription costs, leveraging the same AI budget they already allocate for other tasks.

## Key points

- Connect Codex to a PDF‑to‑MP3 MCP server via Settings → Plugins
- Add a speech API key; only speech generation incurs usage fees
- Ask the MCP to turn an attached PDF into an audiobook using your OpenAI credits

## Why it matters

Enables creators to repurpose existing PDFs into audio format without new subscriptions, expanding content reach and saving on additional AI service costs.
