OP3 MCP Server tools (6)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

op3_downloads_timeseries
Fetch raw download records for a show from OP3 over a date range. Returns individual download events (time, country, app, device). This is the low-level feed behind the other tools. Use it when you need to filter by episode or a specific date window. Keep limit low (records are verbose). For totals or geography summaries, prefer op3_show_downloads / op3_top_countries.
op3_episode_downloads
Get per-episode download counts for a show from OP3: for each recent episode, downloads in the first 1/3/7/30 days after publish and all-time. Good for comparing how episodes perform. Needs a show UUID. Use limit to cap how many episodes come back.
op3_get_show
Look up a podcast show on OP3 and get its UUID, title, podcast GUID, and stats page URL. Pass a show UUID, a podcast:guid, or a base64-encoded feed URL. This is the entry point: most other tools need the show UUID this returns. Set include_episodes to also list episodes (id, title, pubdate).
op3_show_downloads
Get a show's recent download summary from OP3: monthly downloads, a week-by-week breakdown, and the average weekly downloads. Use this for 'how many downloads does my show get' questions. Needs a show UUID (from op3_get_show).
op3_top_apps
Get the top podcast apps and players downloading a show, from OP3, over the last three calendar months. Returns each app with its download count and percent share. Answers 'what apps do my listeners use'. Needs a show UUID.
op3_top_countries
Get the top listener countries (or regions) for a show. NOTE: OP3 has no native geography query, so this counts raw download records and aggregates by country client-side. It is a representative sample, not an exact lifetime total. OP3 returns raw records oldest-first, so to keep the sample recent this tool defaults to the last `window_days` days (90) when you do not pass an explicit start. Each r

op3-mcp

Podcast analytics for AI agents through OP3: downloads over time, listener geography, apps, and per-episode breakdowns. Read-only.

An MCP server for OP3, the Open Podcast Prefix Project. It gives AI assistants podcast analytics that most hosting APIs do not expose: downloads over time, listener geography, the apps people listen in, and per-episode breakdowns.

Read-only by design. OP3 is an analytics service. This server only reads data. It cannot change anything, so it is safe to give an agent.

Why this exists. Most podcast hosts expose almost nothing through their API. Transistor's API, for example, returns download counts and not much else: no geography, no app share, no per-episode recency curve. OP3 has all of that, because it logs each download at the redirect. This server puts that data in front of an agent.

What is OP3?

OP3 is a free, open analytics prefix for podcasts. You add https://op3.dev/e/ in front of your enclosure URLs, and OP3 logs each download before redirecting to your real audio file. It then reports downloads, geography, and app share. Stats pages are public; the API needs a token. See https://op3.dev for details.

If your feed does not use the OP3 prefix yet, OP3 has no data for it. See "Adding the OP3 prefix" below.

Tools

Most tools need a show UUID. Start with op3getshow to turn a feed URL or podcast GUID into a UUID.

Every list tool takes a limit and defaults it low (10) to keep responses small. Agents pay tokens per response.

Setup

1. Get a token

Go to https://op3.dev and sign in.
Open your API token page and copy the token.
For trying things out, OP3 also publishes a shared preview token, preview07ce, which works against public shows.

2. Find your show UUID

If you know your feed URL or podcast GUID, ask the assistant to run op3getshow with it and it will return your UUID. You can also read the UUID from your show's OP3 stats page URL: https://op3.dev/show/{showUuid}.

3. Configure your MCP client
