## Quality 73/100 (new)

### 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: list_categories (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_videos (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_transcript_passages (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,842 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 6 of the 7 days needed

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

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

- tools: 10, about 1,842 tokens to load them all
- tool set hash: e08ce0e11cb5beaa12cffa8af09c4be1
- badge: [![protogrid quality](https://protogrid.dev/badge/tech.buildfeed/buildfeed.svg)](https://protogrid.dev/servers/tech.buildfeed/buildfeed)

## Tools (10)

- `get_stats`: Get aggregate statistics for the entire BuildFeed corpus: total videos, channels, categories, topics, and views; the published-date range; and transcript/TLDR enrichment coverage. Use this for high-level "how much data / how fresh" questions rather than per-video detail.
- `get_transcript`: Get a bounded transcript window for one video. Prefer search_transcript_passages for discovery; use this tool to inspect surrounding context after selecting a video.
- `get_video`: Get full detail for a single BuildFeed video — description, channel info, stats, categories, topics, TLDR, and key takeaways (the raw transcript text itself is excluded). Accepts either an 11-character YouTube video ID or a BuildFeed article slug. Use this after search_videos/list_videos to drill into one specific result.
- `get_weekly_roundup`: Get BuildFeed's weekly roundup content. Without a date, returns the index of available weekly roundups (most recent first) — useful for discovering which weeks exist. With a date (YYYY-MM-DD week key), returns that week's full roundup detail. Use this for "what happened this week" or historical week-by-week summary questions.
- `list_categories`: List all of BuildFeed's video categories (AI, VC, Startup, Product, Design, Tools) with the number of videos in each. Use this to understand the taxonomy before filtering search_videos/list_videos/list_channels by category.
- `list_channels`: List YouTube channels tracked by BuildFeed, with per-channel video counts and categories, sorted by video count descending. Use this to discover which creators BuildFeed covers, optionally filtered to a category.
- `list_topics`: List canonical topic clusters from the full BuildFeed archive, grouped into stable families such as AI & Models, Building, Product, Startups, and Industry. Returns video counts, aliases, content-type distribution, and audience labels.
- `list_videos`: List curated BuildFeed videos, optionally filtered by category and sorted by recency, views, likes, or quality score. Returns compact video records (title, channel, categories, view/like counts, quality score) without transcript or description text. Use this to browse recent/top videos; use search_videos instead when looking for a specific topic.
- `search_transcript_passages`: Search inside transcript passages, returning the most relevant timestamped excerpts across multiple videos. Use this for evidence, quotations, implementation details, or questions whose answer may not appear in a title or summary.
- `search_videos`: Full-text search over BuildFeed's curated AI/startup/VC YouTube video library. Scores videos by keyword match across title, topics, TLDR summary, channel name, and key takeaways, ranked by relevance (then recency). Use this when the user asks about a specific topic, person, product, or company and you need to find relevant videos with summaries — not when you just want to browse everything (use list_videos for that instead).
