Use OndaCast in Claude, ChatGPT and other AI assistants
OndaCast now has a free connector for AI assistants. Ask Claude or any assistant that supports MCP to find a live radio station, a podcast or a free audiobook, and get OndaCast links and cards right in the chat.
More and more of us ask an AI assistant before we open a website. So we built OndaCast a front door for them.
OndaCast now has a free, public connector for AI assistants. Add it once, then ask in plain words:
"Find a calm radio station on OndaCast."
"What's playing on jazz stations in Brazil right now?"
"Show me the top songs this week."
"Find a podcast about astronomy and its latest episodes."
"Is there a free audiobook of Pride and Prejudice?"
The assistant searches OndaCast's live catalogue: 79,000+ radio stations in 220+ countries, 330,000+ podcasts, 25,000+ public-domain audiobooks, live song charts and the radio guide. Every answer comes back with links to OndaCast, so one tap takes you straight to the station, show or book.
What you need
Just one address:
https://ondacast.com/mcp
That's it. No account, no API key, no sign-in. The connector uses the Model Context Protocol (MCP), the open standard that Claude, ChatGPT and a growing list of apps use to talk to outside services. OndaCast is also listed in the official MCP Registry as com.ondacast/ondacast, so apps that browse the registry can find it by name.
Add OndaCast to Claude
In Claude, open Settings → Connectors.
Choose Add custom connector.
Name it OndaCast and paste
https://ondacast.com/mcpas the address.Claude detects that no sign-in is needed. Leave No sign-in selected and click Add.
Optional: under Tool permissions, set the read-only tools to Always allow, so Claude doesn't ask before every search. Leave Add a podcast on Needs approval.
Now start a new chat, check that OndaCast is switched on in the tools menu, and ask away.
Add OndaCast to ChatGPT and other assistants
Any assistant or app that supports MCP connectors can use OndaCast with the same address. Look in its settings for Connectors, Apps, MCP servers or Add custom connector, paste https://ondacast.com/mcp, and choose no authentication. The exact menu names change from app to app and from release to release.
What the assistant can do with OndaCast
Ask about… | What you get |
|---|---|
Radio stations | Stations by name, genre, country or language, with what's playing right now and how many people are listening |
A station | Its location, genres, frequency, the current song, and a link to listen |
Podcasts | Shows by topic or name, with their latest episodes |
Missing podcasts | If a show isn't on OndaCast yet, the assistant can add it from the public podcast directory (with your approval) |
Audiobooks | Free public-domain audiobooks by title or author |
Charts | The most-played songs and artists on OndaCast radio, worldwide or by country |
Radio guide | Which guide shows are on air right now |
OndaCast itself | Up-to-date catalogue figures |
OndaCast cards in the chat
In assistants that support interactive results (MCP Apps), OndaCast answers can show up as cards instead of plain text:
a station card with the logo, location, genres and the song playing now,
a station list for searches,
a podcast card with the five latest episodes,
an audiobook list,
a top 10 chart.
Every card carries the OndaCast logo and name. Tap the logo, a title or Open on OndaCast to open the matching page. Where the assistant allows it, a station card can also play the station right inside the chat through OndaCast's own player. Elsewhere, Listen on OndaCast takes you to the station.
For long listening, like podcast episodes and audiobook chapters, the cards send you to OndaCast. That's where your progress, chapters and favorites live.
Privacy and safety
Read-only. The connector looks things up. Its one action is adding a missing podcast to the catalogue, and assistants like Claude ask you before doing that.
No personal data. OndaCast never sees your conversation, your name or your assistant account. The connector uses no cookies and no sign-in, and we don't keep the content of requests in our logs.
Only OndaCast links. Answers link to OndaCast pages, never to raw stream or feed addresses, and only include stations that play over a secure connection.
Fair limits. The connector has rate limits, so it stays fast for everyone.
Read the details in our Privacy Policy and Terms of Service.
Frequently asked questions
Does it cost anything? No. OndaCast is free, and so is the connector.
Do I need an OndaCast account? No. You only need an account on OndaCast itself to save favorites, follow shows and keep your listening history.
Why does the assistant give me a link instead of playing the music? Chat apps and browsers only start audio after you tap something, and some assistants don't allow players inside chat cards yet. One tap on the link opens the station on OndaCast and it starts playing.
The assistant didn't use OndaCast. What do I do? Mention it by name ("…on OndaCast") and check that the connector is switched on for that chat.
Can I use it in my own app? Yes. Any MCP client can connect to https://ondacast.com/mcp. Please keep to the rate limits and our Terms.
