Connect n8n to TikTok, Reddit and Xiaohongshu data
n8n can read publicly visible posts, comments and profiles on 18 platforms, including TikTok, Reddit and Xiaohongshu through SocialToAI's hosted MCP server: add one address and an API key that n8n sends in a header. Calls cost from 1 credit (≈ $0.002–$0.0033); failed calls are free.
Set up n8n
n8n sends a SocialToAI API key in a header. The key stays where the steps below put it, never in an address or a chat.
- Create a key in the console.
- Add an MCP Client Tool node to an AI Agent and fill in these values.
- Store your key in the Bearer Auth credential, not in the node, then run the workflow.
| MCP Client Tool node | Value |
|---|---|
| Endpoint | https://mcp.socialtoai.com/mcp |
| Server transport | HTTP Streamable |
| Authentication | Bearer Auth |
| Bearer token | <YOUR_API_KEY> |
Check that it works
Ask n8n: “Which SocialToAI tools can you use?” It lists 18 tools; finding and listing them is free. Then ask in plain words: you do not name tools or parameters, the client picks them.
What to ask
A first question on each platform, and the call it makes. The credits are per call; your AI may make a few calls for one answer.
| Platform | Ask | Price key | Credits |
|---|---|---|---|
| TikTok | Search TikTok for videos about "space station". | tiktok.search | 2 |
| Search Reddit for posts about "saturn rings". | reddit.search | 2 | |
| X (Twitter) | Search X for posts about "weather forecast". | x.search | 2 |
| YouTube | Search YouTube for videos about "meteor shower". | youtube.search | 2 |
| Xiaohongshu (RedNote) | Search Xiaohongshu for notes about "咖啡". | xiaohongshu.search | 12 |
| Douyin | Search Douyin for videos about "露营". | douyin.search | 12 |
| Find Instagram accounts about "nike". | instagram.search:user | 3 | |
| Search LinkedIn for posts about "ai agents". | linkedin.search | 2 |
What it costs
Calls cost from 1 credit (≈ $0.002–$0.0033), and every answer states what it charged and the balance left. Failed calls are free; a search that runs and finds nothing is charged as a call. 100 free credits on sign-up, no card; credits never expire and there is no subscription. See pricing.
Questions
Do I need accounts on the platforms?
No. SocialToAI reads what is publicly visible on each platform; you never sign in to them or give a cookie.
Where does the key go?
Where the steps above say (MCP Client Tool node). Create it in the console; it is shown once. It never goes into an address.
Which platforms can it read?
18 platforms: all platforms and what each call costs.
