Hooklayer for n8n

In your n8n workflow, add the "MCP Client" node and configure Hooklayer's URL (https://hooklayer.dev/api/mcp) + Bearer hl_live_ key. The 7 Hooklayer tools (analyze_account, score_hook, viral_remix, trend_pulse, find_viral_template, match_voice, predict_virality) appear in the node's tool dropdown and chain like any other n8n step.

What works in n8n

  • All 7 Hooklayer tools as MCP Client node actions
  • Bearer auth via header injection
  • Chains with n8n's 400+ existing nodes
  • Credentials stored in n8n vault
  • recommended_chain readable by downstream nodes

Setup (60s)

Config file: n8n MCP Client node settings

YAMLCopy + paste
# Inside n8n's MCP Client node:

URL:             https://hooklayer.dev/api/mcp
Transport:       HTTP (Streamable / JSON-RPC 2.0)
Authentication:  Header Auth (n8n credential)

# Create credential of type "Header Auth":
Name:     Authorization
Value:    Bearer hl_live_...

# Once connected, the node's "Tool" dropdown lists:
- analyze_account
- score_hook
- viral_remix
- trend_pulse
- find_viral_template
- match_voice
- predict_virality
  1. 1
    Get your API key

    Sign up at hooklayer.dev/auth/signup for an hl_live_ key. Copy it.

  2. 2
    Create an n8n Header Auth credential

    In n8n: Settings → Credentials → Create New → Header Auth. Name: "Hooklayer Bearer". Value: "Bearer hl_live_..." (with your real key).

  3. 3
    Add the MCP Client node

    In your workflow, add the MCP Client node. Configure it as remote HTTP MCP server. Point at https://hooklayer.dev/api/mcp.

  4. 4
    Pick a tool from the dropdown

    The node's "Tool" dropdown lists Hooklayer's 7 tools. Pick one, configure its inputs (or pass from upstream nodes), and run.

Detect viral TikTok videos and email yourself the analysis

# n8n workflow:
# 1. Cron trigger (daily 9am)
# 2. HTTP Request → TikTok trending feed
# 3. Filter → top 5 by views
# 4. MCP Client (Hooklayer): tool=analyze_account, params={handle: $json.username}
# 5. Email node → send summary to your inbox

Expected: Daily-cadence pipeline. Auto-analyzes top trending creators each morning. Each analyze_account call costs 5 credits — caching keeps daily cost predictable.

Score every TikTok hook saved to a Google Sheet

# n8n workflow:
# 1. Google Sheets trigger (new row)
# 2. MCP Client (Hooklayer): tool=score_hook, params={text: $json.hook, platform: "tiktok"}
# 3. Update sheet with score, percentile, pattern_match, would_fail_because

Expected: Per-hook scoring at scale. Useful for content teams reviewing dozens of drafts/week. 1 credit per call; 24-hour determinism cache means re-scoring is free within the window.

Build a 3-step viral pipeline: analyze → remix → predict

# n8n workflow:
# 1. Manual trigger (input: TikTok URL + your topic)
# 2. MCP Client (Hooklayer): tool=analyze_account, params from input
# 3. MCP Client (Hooklayer): tool=viral_remix, params from analyze response.recommended_chain[2]
# 4. MCP Client (Hooklayer): tool=predict_virality, params={script: $json.fresh_script.scenes.map(s => s.voiceover).join(" ")}
# 5. If predict.virality_score >= 70, save to Notion; else loop back to step 3

Expected: Automated content quality gate. Cost: 5 + 3 + 2 = 10 credits per pipeline run. Quality threshold (70) keeps slop out of your content calendar.

Frequently asked

Which n8n version do I need?

n8n 1.55.0+ for the MCP Client node (released 2026-Q1). Self-hosted users: docker pull n8nio/n8n:latest. Cloud users: it's in the default node set.

Can I use Hooklayer with the n8n MCP Server node (not Client)?

No — those are different things. MCP Server node EXPOSES n8n workflows as MCP tools (for Claude/Cursor to call). MCP Client node CALLS external MCP servers (like Hooklayer). You want the Client node.

How do I pass output from one Hooklayer tool to the next?

Use n8n expression syntax: {{ $json.recommended_chain[0].params.handle }}. analyze_account returns recommended_chain[] with pre-filled params; you can wire each step's params directly from the previous node's output.

Will n8n retry on transient failures?

Yes — n8n's built-in retry logic catches 5xx errors. Hooklayer returns 502/503 cleanly when upstream services fail (no credits charged). Configure retry-on-fail with a 3-attempt limit and exponential backoff for safety.

Can I rate-limit my n8n flows to stay within Hooklayer's tier?

Use n8n's "Wait" node between Hooklayer calls if you're on the Starter tier (60 req/min). Pro/Agency tiers (300 / 1,000 req/min) almost never need throttling — n8n's default rate is well below those limits.

How do I monitor Hooklayer credit burn in n8n?

Every Hooklayer response includes credits_remaining.total in the JSON. Add a small "IF" node after each MCP Client call: if credits_remaining.total < 100, send a Slack/email alert to top up.
