You need dedicated capabilities in the Podcasts domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Free / Open Source).
Podcast analytics from OP3, the Open Podcast Prefix Project: downloads over time, listener geography, app share, and per-episode breakdowns. Read-only by design.
Apple Podcasts Connect owner analytics over Reporter: plays, followers, episodes. Read-only.
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_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_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.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Op3 MCP is categorized under Podcasts and uses a local stdio subprocess. In contrast, Apple Podcasts MCP Server belongs to Podcasts using local stdio subprocess. Select Op3 MCP when you need capabilities focused on podcasts and Apple Podcasts MCP Server when you require tools for podcasts.
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 result has a download count and percent share. Needs a show UUID. Keep max_records modest to stay fast and within rate limits.
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.
