The flagship

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.

recommended_chain — fired automatically
#1
match_voice

High-signal voice DNA — consistent across top 5 videos

#2
trend_pulse

Verify their formula maps to current trends in challenge_videos

#3
viral_remix

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.

The wedge

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.

The toolkit

Seven tools, one Bearer token.

Every endpoint is also exposed as an MCP tool — Claude Desktop, Cursor, n8n, custom agents. One config, full toolkit.
