Category Search and Retrieval
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 → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability55
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 827 tokens (~275/item across 3 items; 3 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 Management10
- Stability observed for 3 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 5 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
youtube_search Search YouTube (SerpAPI) ~238
Search YouTube live via SerpAPI. Returns video_results (videos), plus channels, playlists, movies and related searches. Each video result's id is the YouTube video id — feed it as `v` to youtube_video (details, related videos, comments) and to youtube_transcript. `sp` carries SerpAPI filter and next-page tokens from a prior result for pagination / refined filtering.
| Name | Type | Req | Description |
|---|---|---|---|
| gl | string | – | Country code for the search, e.g. 'us', 'uk', 'de'. |
| hl | string | – | Language code, e.g. 'en', 'es', 'pt-br'. |
| no_cache | boolean | – | Force a fresh SerpAPI fetch and bypass this server's result cache. Default false. |
| search_query | string | yes | Search query for YouTube (required). Same syntax as the YouTube search box. |
| sp | string | – | Filter / pagination token from a prior result: carries YouTube search filters and the next-page token. |
| zero_trace | boolean | – | Enterprise-only ZeroTrace mode: don't store search params/metadata on SerpAPI. Default false. |
No output schema declared.
No examples provided.
youtube_transcript Get YouTube Transcript (SerpAPI) ~280
Fetch a YouTube video's transcript via SerpAPI. `v` is the video id from a youtube_search result. Pick a track with language_code (default 'en' — use the video's own language), and optionally title and type ('asr' for auto-generated captions). When the requested track doesn't exist the tool falls back once to an available track (same language first, manual before auto-generated) and says so in `note`.
| Name | Type | Req | Description |
|---|---|---|---|
| language_code | string | – | Transcript language code, e.g. 'en', 'pl'. Default 'en' — pass the video's own language. If that track doesn't exist, an available one is used instead and `note` says which. |
| no_cache | boolean | – | Force a fresh SerpAPI fetch and bypass this server's result cache. Default false. |
| title | string | – | Transcript track title to select when multiple tracks exist. |
| type | string | – | Transcript track type: 'asr' for auto-generated captions; omit for manual captions. If that track doesn't exist, an available one is used instead and `note` says which. |
| v | string | yes | YouTube video id (required) — the id from a youtube_search result. |
| zero_trace | boolean | – | Enterprise-only ZeroTrace mode: don't store search params/metadata on SerpAPI. Default false. |
No output schema declared.
No examples provided.
youtube_video Get YouTube Video (SerpAPI) ~209
Fetch a single YouTube video by id via SerpAPI: details, related videos, comments and replies. `v` is the video id from a youtube_search video_results entry. Page related videos / comments / replies with next_page_token from a prior result.
| Name | Type | Req | Description |
|---|---|---|---|
| gl | string | – | Country code for the search, e.g. 'us', 'uk', 'de'. |
| hl | string | – | Language code, e.g. 'en', 'es', 'pt-br'. |
| next_page_token | string | – | Token from a prior result to page through related videos, comments, or replies. |
| no_cache | boolean | – | Force a fresh SerpAPI fetch and bypass this server's result cache. Default false. |
| v | string | yes | YouTube video id (required), e.g. the id from a youtube_search video_results entry. |
| zero_trace | boolean | – | Enterprise-only ZeroTrace mode: don't store search params/metadata on SerpAPI. Default false. |
No output schema declared.

How do I install the YouTube MCP server?
YouTube MCP is a hosted endpoint at https://mcp.wondel.ai/youtube/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
