## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 94/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 2244 tokens (~86/item across 26 items; 25 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 82/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 46% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

## MCP tools (25)

### `search_podcasts` (~80 tokens)

Search PodLearn library AND PodcastIndex.org (4M+ podcasts) by keyword. Also resolves Spotify/Apple Podcasts URLs. Returns rows tagged with `source: local|podcastindex|spotify`. First move when the user names a podcast/host but you don't have its id.

Input parameters:

- `query` (string, required): Search keywords or a podcast URL

### `list_podcasts` (~73 tokens)

List podcasts already in the PodLearn library, optionally filtered by category. Returns most-recently-added first. For discovery beyond the library use search_podcasts.

Input parameters:

- `category` (string): Filter by category (e.g. "Technology")
- `limit` (integer)
- `offset` (integer)

### `get_podcast_details` (~58 tokens)

Fetch full metadata for one podcast in the PodLearn library, including its episode count. The podcast must already be in the local DB (source=local in search_podcasts results).

Input parameters:

- `podcast_id` (integer, required): Local podcast id

### `search_episodes` (~112 tokens)

Cross-podcast episode search by title/description AND parent podcast name/author. Returns local episodes only — for podcasts discoverable on PodcastIndex that aren't yet ingested, use list_feed_episodes instead. `status: "transcribed"` filters to ready-to-read; `status: "untranscribed"` to available-to-transcribe.

Input parameters:

- `limit` (integer)
- `offset` (integer)
- `query` (string, required): Topic, keyword, or host name
- `status` (string)

### `list_feed_episodes` (~169 tokens)

Fetch the canonical episode list for a podcast directly from PodcastIndex (the upstream RSS index). NO COST — pure discovery. Each episode is enriched with `in_library`, `episode_id` (if already ingested), and `transcription_status`. For episodes you want to ingest: call transcribe_url(audio_url, title, feed_id, podcast_name) — passing feed_id/podcast_name lands the episode under its real show. For episodes already in_library, use start_transcription(episode_id) instead.

Input parameters:

- `before` (integer): Unix seconds — published BEFORE (pagination)
- `feed_id` (string, required): PodcastIndex feed_id (the `id` from a search_podcasts result)
- `max` (integer)
- `since` (integer): Unix seconds — published AFTER

### `list_episodes` (~96 tokens)

List episodes already in the local DB for a specific podcast. Requires podcast_id (use search_podcasts first if you only have a name). For cross-podcast search use search_episodes; for canonical PodcastIndex listings use list_feed_episodes.

Input parameters:

- `limit` (integer)
- `offset` (integer)
- `podcast_id` (integer, required): Local podcast_id from search_podcasts
- `status` (string)

### `get_episode_details` (~95 tokens)

Fetch full metadata for one episode including transcription_status and lesson_generation_status. Tells you whether get_transcription is ready or you need to transcribe first: start_transcription(episode_id) for an in-library episode (inherits its existing show/artwork/feed linkage automatically) or transcribe_url(audio_url, title, feed_id, podcast_name) for a URL not yet in the library.

Input parameters:

- `episode_id` (string, required)

### `transcribe_url` (~328 tokens)

Ingest and transcribe an EXTERNAL / arbitrary audio URL — a URL the user pasted, or audio not reachable through the index. Creates a STANDALONE episode row. If the episode is already in the library (it has an episode_id), prefer start_transcription(episode_id) instead — it inherits the episode's existing show, artwork, and feed linkage automatically. Consumes 1 transcription credit, or one unit of subscription quota; the credit is refunded automatically if transcription fails. Pass feed_id / podcast_name when you already know the parent show (e.g. from search_podcasts or list_feed_episodes) so the episode lands under its real show instead of appearing as unidentified "External audio". Returns the new episode_id. Transcription is asynchronous on the fallback path — poll get_episode_details until transcription_status is "completed".

Input parameters:

- `audio_url` (string, required): Direct audio URL (mp3, m4a, or platform URL)
- `feed_id` (string): Optional: local podcasts.id / PodcastIndex feed id of the parent show, if known. Looked up only — never creates a show.
- `language` (string): BCP-47 hint (e.g. "en", "he"). Auto-detect if omitted.
- `podcast_id` (integer): Existing parent podcast_id, if any
- `podcast_name` (string): Optional: exact parent show title, if known and feed_id is unavailable. Matched only when it resolves to EXACTLY ONE existing show.
- `title` (string, required): Episode title — shown in the user's library

### `transcribe_feed` (~195 tokens)

Bulk/season transcription — kick off transcription for up to `max` (cap 25) not-yet-transcribed episodes of a podcast feed in ONE call. Pass the `feed_id` from search_podcasts / list_feed_episodes. Already-transcribed episodes are skipped free. COSTS 1 credit per newly enqueued episode (or subscription quota) — CONFIRM the cost with the user first. Enqueue-and-poll: returns each enqueued episode_id; poll get_episode_details until transcription_status is "completed".

Input parameters:

- `before` (integer): Optional unix-seconds; only episodes published BEFORE (page back)
- `feed_id` (string, required): PodcastIndex feed id (from a search_podcasts / list_feed_episodes result)
- `max` (integer): Max episodes to enqueue (default 10, cap 25)
- `since` (integer): Optional unix-seconds; only episodes published AFTER

### `start_transcription` (~89 tokens)

Kick off transcription on an episode ALREADY in the library. Use only when the episode row exists and transcription_status is not "completed". Inherits the episode's existing show, artwork, and feed linkage automatically — no need to pass podcast context. For audio not yet in the library, use transcribe_url. COSTS 1 CREDIT (or subscription quota).

Input parameters:

- `episode_id` (string, required)

### `get_transcription` (~149 tokens)

Fetch transcript text for a completed episode. PAGINATED — returns up to 120,000 characters per call (Claude.ai/Desktop caps a tool result at ~150k chars). Most transcripts fit in one call; only very long episodes page. If the response has `has_more: true`, call again with `offset: <next_offset>`. For focused look-up (a topic, quote, timestamp) prefer search_transcription.

Input parameters:

- `episode_id` (string, required)
- `max_chars` (integer): Max characters to return this call (default & max 120000).
- `offset` (integer): Character offset to start from (default 0). Use next_offset from a prior page.

### `search_transcription` (~72 tokens)

Keyword search WITHIN a single episode's transcript. Returns matching chunks with surrounding context. Use instead of get_transcription when the user asked about a specific topic — server does this faster + cheaper on context.

Input parameters:

- `episode_id` (string, required)
- `query` (string, required): Topic, phrase, or speaker name

### `get_transcription_segments` (~47 tokens)

Fetch timestamped transcript segments. Use when the user wants timestamps — "jump to where they discuss X", chapter boundaries, durations of specific parts.

Input parameters:

- `episode_id` (string, required)

### `list_lessons` (~32 tokens)

List the calling user's saved AI-generated lessons.

Input parameters:

- `limit` (integer)
- `offset` (integer)

### `get_lesson_content` (~55 tokens)

Fetch the full body of one AI-generated lesson (title, summary, key takeaways, structured sections). Use to retrieve prior synthesis — for creating a NEW one call generate_lesson.

Input parameters:

- `lesson_id` (string, required)

### `generate_lesson` (~76 tokens)

Generate a structured AI lesson (summary, key takeaways, sections) from a completed transcription. Requires the episode to have transcription_status "completed". Consumes 1 credit, or one unit of subscription quota, on first generation for an episode; subsequent calls return the cached lesson at no cost.

Input parameters:

- `episode_id` (string, required)

### `get_subscription_status` (~24 tokens)

Get the caller's subscription plan + active/expired status + period end.

### `get_user_credits` (~18 tokens)

Get the caller's remaining transcription credits.

### `get_episode_usage` (~43 tokens)

Get the caller's episode-access usage stats — how many episodes they've transcribed/read this billing period.

Input parameters:

- `limit` (integer)
- `offset` (integer)

### `get_saved_items` (~20 tokens)

List the caller's saved/bookmarked episodes and lessons.

### `save_item` (~41 tokens)

Bookmark an episode or lesson for the caller.

Input parameters:

- `item_id` (string, required): UUID of the episode or lesson to save
- `item_type` (string, required)

### `remove_saved_item` (~44 tokens)

Permanently remove a saved/bookmarked episode or lesson from the caller's collection. The saved_item_id comes from get_saved_items.

Input parameters:

- `saved_item_id` (string, required)

### `generate_linkedin_post` (~72 tokens)

Turn an already-generated lesson into a LinkedIn-ready share post. Pass lesson_id directly OR episode_id (uses the most recent lesson generated by the caller for that episode). Lesson must exist — chain after generate_lesson if needed.

Input parameters:

- `episode_id` (string)
- `lesson_id` (string)

### `search_youtube` (~110 tokens)

Discover YouTube videos by topic/keyword across all of YouTube. Use when the user wants to learn from a talk/interview/lecture and has no URL — especially when search_podcasts / search_episodes find nothing (much long-form content is YouTube-first). NO COST: pure discovery. Returns rows with a ready-to-transcribe `url`; to ingest one, confirm cost and call transcribe_url(url, title).

Input parameters:

- `max` (integer)
- `query` (string, required)

### `browse_episodes` (~76 tokens)

Browse episodes

Open an interactive episode picker (card grid with thumbnails) for the user to pick an episode to read. On hosts that render MCP Apps the grid is clickable; everywhere else a markdown table is returned. Optional query filters by title/host.

Input parameters:

- `limit` (integer)
- `query` (string): Optional title/host filter
