## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: summarize_youtube_video (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_youtube_transcript (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); format_json (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 664 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 664 tokens to load them all
- tool set hash: ee4b0e370ea0e3ef18bbb68c802505c6
- tools last changed: 2026-09-30T03:08:44.302Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.JonTelep/summarize-vid.svg)](https://protogrid.dev/servers/io.github.JonTelep/summarize-vid)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-30 `format_json` added
  - 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.
- 2026-09-24 `summarize_youtube_video` changed (description)
  - before: 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.
  - after: 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.

## Tools (4)

- `format_json`: 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.
- `get_youtube_transcript`: 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.
- `list_new_channel_videos`: 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.
- `summarize_youtube_video`: 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.
