_ is it live, free and safe measured by this hub
Is buildfeed live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is buildfeed free to use?
Yes — the hub reached it with no key and no payment.
What tools does buildfeed have?
10 tools: list_videos, get_video, get_transcript, search_videos, search_transcript_passages, list_channels, list_topics, list_categories, ….
Is buildfeed safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_categories open 1h ago

    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.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • get_stats open 1h ago

    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.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • get_weekly_roundup open 1h ago

    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.

  },
  "additionalProperties": false
}
    arguments 17 lines
  • list_videos unknown never probed

    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.

  },
  "additionalProperties": false
}
    arguments 40 lines
  • get_video unknown never probed

    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.

    }
  },
  "additionalProperties": false
}
    arguments 15 lines
  • get_transcript unknown never probed

    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.

  },
  "additionalProperties": false

    arguments 27 lines
  • search_videos unknown never probed

    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).

  • search_transcript_passages unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 7b9aa013a0532966.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7b9aa013a0532966/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/7b9aa013a0532966/badge.svg)](https://brick.blue/agent/7b9aa013a0532966?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
