Score hooks. Predict virality.
Inside Claude & ChatGPT.
Hooklayer is the viral-content intelligence MCP that runs inside Claude (custom connector) and ChatGPT (app directory). 14 tools that test hooks, predict virality, find templates, analyze creators, research TikTok Shop products, and track competitor changes over time, inside your AI workspace, not another SaaS tab. Test the angle before you waste a day filming. Real viral TikTok, Instagram Reels, and YouTube Shorts, researched live.

Hooklayer is a Model Context Protocol (MCP) server that exposes real viral TikTok, Instagram Reels, and YouTube video research as 14 agent-callable tools organized into 6 workflow layers: Score (hook + virality scoring), Research (trends + templates + video search), Analyze (creator account + voice extraction), Shop (TikTok Shop product scout + product analysis), Generate (URL-to-script remix + brief-to-blueprint), and Watch (track creators, detect changes over time).
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 listed 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 on the Anthropic Official MCP Registry, Cursor Directory, Smithery, 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 app 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 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": "@example_creator",
"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.

}'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.
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: about $0.10 on a top-up, less on a plan.
Analyze 50 competitors. Ship 30 ads a week.
Agency tier ($99/mo) pools 3,000 credits across your team for 5-15 client rosters. Weekly competitor sweeps + batch hook testing + client-specific script generation, one flat rate.
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.
14 tools. 5 layers. One Bearer token.
Score → Research → Analyze → Shop → 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/scoreScore a hook 0–100 against proven viral patterns. Returns 3 stronger rewrites + matched pattern + percentile.
POST /v1/predictScore a draft script for viral potential. Adversarial attack-vector check + SHIP / REWORK / NO-GO verdict.
Research
Find what is already working.GET /v1/trendsRising opportunities + saturated patterns per niche. Format / hook / style trends, not news topics.
GET /v1/templatesNiche-fit ranked templates with hook patterns, format structures, and example URLs. Optional query narrows to a specific angle.
GET /v1/searchKeyword search across real viral videos. Region + window + min-views filters. Auto-retries when defaults return empty.
Analyze
Read creators and voices.POST /v1/account/analyzeTikTok handle → full Viral DNA (scores, format fingerprint, steal map) + recommended_chain pre-filling your next 3 tool calls.
POST /v1/voice/matchExtract a creator's voice signature from reference samples. Returns DNA metrics + voice fingerprint your agent reuses across drafts.
POST /v1/watch/accountSet a baseline snapshot for a creator so later calls can diff against it. Cache-hit path charges 0.
GET /v1/watch/changesWhat changed on a watched account since the baseline, ranked by importance, including what did not change.
GET /v1/watchesList your tracked accounts. Pure database read, never touches the credit ledger.
Shop
Decide what is worth filming.GET /v1/product/scoutScan a TikTok Shop niche. Returns ranked products with provider evidence and a PROMOTE / WATCH / SKIP verdict carrying the reason it was reached. Deterministic scoring, no LLM in the ranking path.
POST /v1/product/analyzeFull teardown of one product: buyer language from real reviews, what objections to answer on camera, and the creative next step. Never returns revenue or GMV.
Generate
Produce in-voice scripts.POST /v1/remixURL or transcript → fresh script mirroring the original viral DNA. Scene structure, energy pattern, camera shots, native CTA rotation.
POST /v1/brief-to-blueprintTurn a brand brief into a shoot-ready blueprint. Chains templates, trends, hook scoring and prediction internally so one call covers the whole step.
Pick the product before you write the hook
Two of the 14 tools cover TikTok Shop. product_scout scans a niche and ranks what it finds, returning a PROMOTE, WATCH or SKIP verdict per product with the signal that decided it. analyze_product goes deep on one listing and surfaces the recurring buyer objections, which are the script. Deterministic ranking, no model in the scoring path.
Built for agencies and content creators who ship at volume.
Every Hooklayer tool is callable from the n8n MCP client node. 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.

Hooklayer, answered.
What is Hooklayer?
Hooklayer is the viral-content intelligence MCP for Claude and ChatGPT. It exposes real viral-video research as 14 agent-callable tools organized into 6 layers: score hooks + predict virality (Score), find templates + surface trends + search videos (Research), analyze accounts + match creator voices (Analyze), scout and analyze TikTok Shop products (Shop), remix viral URLs into fresh scripts + turn briefs into blueprints (Generate), and track competitor creators for change detection over time (Watch).
