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 Security63
- 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 10 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability77
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1095 tokens (~109/item across 10 items; 10 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage86
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 58% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 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
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 18 Oct 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.
- 16 Oct 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

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 →
get_stats ~63
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_transcript ~71
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 ~116
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.

No examples provided.
list_videos ~183
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Restrict to one category: AI, VC, Startup, Product, Design, or Tools. |
| limit | integer | – | Max videos to return (default 20, hard cap 50). |

search_videos ~197
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).
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Restrict results to one category: AI, VC, Startup, Product, Design, or Tools. |
| limit | integer | – | Max results to return (default 20, hard cap 50). |
| query | string | yes | 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). |

How do I install the BuildFeed MCP server?
BuildFeed is a hosted endpoint at https://buildfeed.tech/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the BuildFeed MCP server?
BuildFeed is an MCP server listed in the public MCP registry as tech.buildfeed/buildfeed. Startup, product, and design takes from curated tech YouTube, with timestamped transcript passages. This page covers its hosted endpoint (https://buildfeed.tech/api/mcp).
Is the BuildFeed MCP server safe to use?
BuildFeed scores 68 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the BuildFeed MCP server expose?
BuildFeed exposes 10 tools: search_videos, search_transcript_passages, get_transcript, list_videos, get_video, and 5 more. Their descriptions and schemas cost roughly 1,095 tokens of context every time the server is loaded.
Does the BuildFeed MCP server require authentication?
No. We connected to BuildFeed without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the BuildFeed MCP server still maintained?
BuildFeed is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
