# Connect Dify to TikTok, Reddit and Xiaohongshu data

Dify 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 Dify sends in a header. Calls cost from 1 credit (≈ $0.002–$0.0033); failed calls are free.

## Set up Dify

Dify 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.
- In Dify, open Tools → MCP, add an HTTP server and fill in these values; the header is under the advanced settings.
- Replace <YOUR_API_KEY> with your key and save. The tools can then be added to an agent or a workflow.

| Tools → MCP → Add MCP Server (HTTP) | Value |
| --- | --- |
| Server URL | `https://mcp.socialtoai.com/mcp` |
| Name | `SocialToAI` |
| Server identifier | `socialtoai` |
| Headers | `Authorization: Bearer <YOUR_API_KEY>` |

## Check that it works

Ask Dify: “Which SocialToAI tools can you use?” It lists 16 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](https://socialtoai.com/platforms/tiktok.md) | Search TikTok for videos about "space station". | `tiktok.search` | 2 |
| [Reddit](https://socialtoai.com/platforms/reddit.md) | Search Reddit for posts about "saturn rings". | `reddit.search` | 2 |
| [X (Twitter)](https://socialtoai.com/platforms/x.md) | Search X for posts about "weather forecast". | `x.search` | 2 |
| [YouTube](https://socialtoai.com/platforms/youtube.md) | Search YouTube for videos about "meteor shower". | `youtube.search` | 2 |
| [Xiaohongshu (RedNote)](https://socialtoai.com/platforms/xiaohongshu.md) | Search Xiaohongshu for notes about "咖啡". | `xiaohongshu.search` | 12 |

## 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](https://socialtoai.com/pricing.md).

## 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 (Tools → MCP → Add MCP Server (HTTP)). Create it in the console; it is shown once. It never goes into an address.
