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 Security57
- 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 4 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 is enforced; there's no plaintext access path. View diagnostics → Pass
- 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 Usability69
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 493 tokens (~123/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 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 supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
format_json ~117
Validate raw JSON and return it pretty-printed or minified. `pretty` (default true) uses two-space indentation; false minifies. `sort_keys` (default false) sorts object keys alphabetically and leaves array order alone. Input is capped at 1 MB. Invalid JSON raises with the line and column and is not charged. Pay-per-call via x402 (USDC on Base), no account or API key.
| Name | Type | Req | Description |
|---|---|---|---|
| pretty | boolean | – | – |
| sort_keys | boolean | – | – |
| text | string | yes | – |
No output schema declared.
No examples provided.
get_youtube_transcript ~88
Fetch the raw transcript text of a YouTube video (no model run — the cheaper SKU), in any of 100+ languages (`language` param, BCP-47). Pay-per-call via x402 (USDC on Base), no account. A video without captions returns an error and is not charged.
| Name | Type | Req | Description |
|---|---|---|---|
| language | string | – | – |
| url | string | yes | – |
No output schema declared.
No examples provided.
list_new_channel_videos ~157
New videos on a YouTube channel since your last poll — stateless channel monitoring, no accounts or webhooks. Pass a channel URL, @handle, or channel id, plus an optional cursor (`since_video_id` or `since`, an ISO 8601 timezone-aware timestamp) from your last call. Returns new video ids/titles/publish times, newest first, plus `newest_video_id` to use as your next cursor. Pay-per-call via x402 (USDC on Base), no account or API key. An unresolvable channel or a naive `since` timestamp returns an error and is not charged.
| Name | Type | Req | Description |
|---|---|---|---|
| channel | string | yes | – |
| since | – | – | – |
| since_video_id | – | – | – |
No output schema declared.
No examples provided.
summarize_youtube_video ~131
Summarize a YouTube video with Claude and return the summary text, in any of 100+ output languages (`language` param, BCP-47). Pay-per-call via x402 (USDC on Base) — no account or API key. Cheaper than pulling the full transcript into your own context. A bad URL or a video without captions returns an error and is not charged. New videos up to 60 minutes; longer ones (or ones whose length can't be determined) return an error and are not charged.
| Name | Type | Req | Description |
