Trust breakdown (6 categories)

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. How we score →

Endpoint Security80

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability75

AI-judged instruction clarity (excellent).Pass
Context-footprint check failed: tool/resource definitions use about 688 tokens (~172/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage100

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
100% of tool parameters carry a description.Pass
Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Tool Tokens

get_channel_transcripts Get Channel Transcripts ~183

Get transcripts for a YouTube channel's most recent videos (newest first) as timestamped markdown, one section per video. Use for research across a creator's recent output; for one known video use get_transcript. Read-only; requires an API key. Charges 1 credit per video that returns a transcript, including repeat calls; videos without captions are skipped free. A 10-video call typically costs up to 10 credits, so start with a small limit. Rate limit: 5 requests per 10 seconds.

Input Output Examples

Name	Type	Req	Description
limit	integer	—	Number of most-recent videos to fetch, 1-50 (default 10). Upper bound on the credit charge for this call.

No examples provided.

get_playlist_transcripts Get Playlist Transcripts ~183

Get transcripts for the videos in a YouTube playlist (in playlist order) as timestamped markdown, one section per video. Use for working through a course, series, or curated list; for one known video use get_transcript. Read-only; requires an API key. Charges 1 credit per video that returns a transcript, including repeat calls; videos without captions are skipped free. A 10-video call typically costs up to 10 credits, so start with a small limit. Rate limit: 5 requests per 10 seconds.

Input Output Examples

Name	Type	Req	Description
limit	integer	—	Number of videos to fetch from the start of the playlist, 1-50 (default 10). Upper bound on the credit charge for this call.

get_transcript Get YouTube Transcript ~134

Get the full transcript of a single YouTube video as timestamped markdown. Read-only: fetches existing captions, modifies nothing. Requires an API key; each successful call charges 1 credit, including repeat calls for the same video, so reuse a transcript already in context instead of re-fetching. Videos without captions return an error and cost nothing. Rate limit: 5 requests per 10 seconds.

Input Output Examples

Name	Type	Req	Description
video	string	yes	YouTube video ID (e.g. dQw4w9WgXcQ) or full video URL (youtube.com/watch?v=... or youtu.be/... forms)

creditsUsed	number	yes	Credits charged for this call
title	string	yes	Video title
transcript	string	yes	Full transcript as timestamped markdown
videoId	string	yes	YouTube video ID

No examples provided.

polish_transcript Polish YouTube Transcript ~188

Get a cleaned-up transcript of a YouTube video's auto-generated captions: punctuation and capitalisation restored, filler and false starts removed, paragraphs added, misheard names fixed, faithful to what was said. Use when raw captions are too messy to read or quote; for a plain transcript use get_transcript. Read-only; requires an API key. Each call charges credits by transcript length (about 3 per 1,000 words, minimum 5), including repeat calls, so keep the result in context. Human-uploaded captions (already clean) and transcripts over ~7,000 words return an error without charging. Rate limit: 5 requests per 10 seconds.

Input Output Examples

Name	Type	Req	Description
video	string	yes	YouTube video ID (e.g. dQw4w9WgXcQ) or full video URL (youtube.com/watch?v=... or youtu.be/... forms)

Name	Type	Req	Description
creditsRemaining	number	yes	Account balance after this call
creditsUsed	number	yes	Credits charged for this call (scales by length)
title	string	yes	Video title
transcript	string	yes	Cleaned transcript as timestamped markdown
videoId	string	yes	YouTube video ID

No examples provided.
