# Score hooks. Predict virality.

Inside Claude & ChatGPT.

Hooklayer is the viral-content intelligence MCP that runs inside Claude (custom connector) and ChatGPT (approved directory). 9 tools that test hooks, predict virality, find templates, and analyze creators , inside your AI workspace, not another SaaS tab. Test the angle before you waste a day filming. 100K+ viral TikTok, Instagram Reels, and YouTube Shorts indexed.

[98/100 quality scoreon Smithery](https://server.smithery.ai/khan-ashifur/hooklayer)

**Hooklayer is a Model Context Protocol (MCP) server** that exposes 100,000+ analyzed viral TikTok, Instagram Reels, and YouTube videos as **9 agent-callable tools** organized into 4 workflow layers: *Score* (hook + virality scoring), *Research* (trends + templates + video search), *Analyze* (creator account + voice extraction), and *Generate* (URL-to-script remix).

Unlike content-generation tools (Arcads, Creatify, Higgsfield, Predis), Hooklayer is positioned for content **testing**, score the hook before you shoot, predict the virality before you film, find proven templates before you write. Per Kit's April 2026 creator survey (n=550), **82.7%** of creators report wanting AI ideation/research partners vs **39.3%** who want email drafting. Hooklayer meets them **inside Claude AND ChatGPT** (a combined ~85% creator-tool footprint) instead of asking them to open another dashboard tab.

Live as an **approved connector inside ChatGPT** (install from the connector directory, OAuth handled automatically) and as a **custom MCP connector inside Claude** (paste https://hooklayer.dev/api/mcp, approve OAuth). Also listed in 6 MCP directories: **Anthropic Official MCP Registry, Cursor Directory, Smithery** (98/100 quality score), **Glama, MCP.so, and punkpeye/awesome-mcp-servers**. Free to start, no card. Median hook-scoring latency: **<400ms**. Also works with Cursor, the n8n MCP node, and any MCP 2024-11-05 or 2025-06-18 compliant client.

## Live in Claude as a custom connector.

Live in ChatGPT via the approved directory.

Watch the 60-second walkthrough for your AI client, hit install, and start scoring hooks in your next chat. Claude uses a manual custom-connector setup (paste one URL). ChatGPT installs one-click from its approved connector directory.

Prefer to try it first? The [playground](/hooklayer/playground) runs the full agentic chain on any TikTok handle, no signup, no card.

## One tool. The whole agentic chain.

`analyze_account`

takes one TikTok handle and returns deep intelligence plus a `recommended_chain`

field , pre-filled next-tool calls your agent fires automatically. One call in, four calls out.

```
POST /v1/account/analyze

{
  "handle": "@mrbeast",
  "platform": "tiktok"
}
```

High-signal voice DNA, consistent across top 5 videos

Verify their formula maps to current trends in challenge_videos

Their #2 video has the highest copyable structure

Claude reads `recommended_chain`

and calls match_voice → trend_pulse → viral_remix on its own. No prompt engineering.

## Stop shipping AI slop.

Every n8n / Claude / Cursor content workflow has the same problem: generic LLM calls produce hooks that start with "Hey guys! Today I want to talk about..." and get suppressed by every algorithm.

Hooklayer sits between the LLM and the publish step. Score every hook against proven viral patterns. Reject anything below 70. Auto-rewrite to 85+. One MCP call, one credit.

```
curl -X POST https://hooklayer.dev/v1/hook/score \
  -H "Authorization: Bearer hl_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "text": "3 things I wish I knew",
    "platform": "tiktok"
  }'
```

## Not just Claude power users.

Hooklayer scores hooks, predicts virality, and extracts Viral DNA the same way for every user, but the workflow shape changes by role. Three audience-specific guides below.

[For DTC marketersSee the DTC workflow guide](/hooklayer/for-teams/dtc-marketers)

### Score every hook before you brief the shoot.

DTC creative teams use Hooklayer to score 10 hook variants in 30 seconds, analyze 5 competitors in 2 minutes, and remix viral URLs into briefable scripts. Cost per test: ~$0.02.

[For creative agenciesSee the agency workflow guide](/hooklayer/for-teams/creative-agencies)

### Analyze 50 competitors. Ship 30 ads a week.

Agency tier ($499/mo) pools 32,000 credits across your team for 5-15 client rosters. Weekly competitor sweeps + batch hook testing + client-specific script generation, one flat rate.

[For strategists + researchersSee the research workflow guide](/hooklayer/for-teams/researchers)

### Deep viral research with rubrics, not vibes.

Every score returns 6 named signals with evidence quotes suitable for citation. 8 attack vectors documented. Provenance blocks on every response. Rubric-based, not black-box.

## 9 tools. 4 layers. One Bearer token.

Score → Research → Analyze → Generate. Every layer exposed as both REST endpoints and MCP tools, so Claude Desktop, Cursor, and n8n hit the same surface your scripts do.

### Score

Test before you post.`POST /v1/hook/score`

Score a hook 0–100 against proven viral patterns. Returns 3 stronger rewrites + matched pattern + percentile.

`POST /v1/predict`

Score a draft script for viral potential. Adversarial attack-vector check + SHIP / REWORK / NO-GO verdict.

### Research

Find what is already working.`GET /v1/trends`

Rising opportunities + saturated patterns per niche. Format / hook / style trends, not news topics.

`GET /v1/templates`

Niche-fit ranked templates with hook patterns, format structures, and example URLs. Optional query narrows to a specific angle.

`GET /v1/search`

Keyword search across 100K+ viral videos. Region + window + min-views filters. Auto-retries when defaults return empty.

### Analyze

Read creators and voices.`POST /v1/account/analyze`

TikTok handle → full Viral DNA (scores, format fingerprint, steal map) + recommended_chain pre-filling your next 3 tool calls.

`POST /v1/voice/match`

Extract a creator's voice signature from reference samples. Returns DNA metrics + voice fingerprint your agent reuses across drafts.

### Generate

Produce in-voice scripts.`POST /v1/remix`

URL or transcript → fresh script mirroring the original viral DNA. Scene structure, energy pattern, camera shots, native CTA rotation.

## Built for agencies and content creators who ship at volume.

Every Hooklayer tool is callable from the [n8n MCP client node](https://docs.n8n.io/integrations/builtin/cluster-nodes/root-nodes/n8n-nodes-langchain.mcpclienttool/). Point it at `https://hooklayer.dev/api/mcp`

, add your Bearer token, and every tool becomes a node in your workflow — chainable to Slack, Notion, Airtable, Google Sheets, or a webhook.
