Authorization (optional)

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

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.

This tool takes no arguments.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

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.

Argument	Type	Description

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.

Argument	Type	Description

List curated BuildFeed videos, optionally filtered by category and sorted by recency, views, likes, or quality score.

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).

Argument	Type	Description
limit	integer	Max results to return (default 20, hard cap 50).
query*	string	Search keywords, e.g. "Claude agents", "seed fundraising", "Figma design systems".
since	string	Only videos published on or after this ISO 8601 date (reads the archive index).
category	string	Restrict results to one category: AI, VC, Startup, Product, Design, or Tools.
