CartViral

CartViral MCP Server

AI product videos for e-commerce, from any AI agent. CartViral turns a product page into ready-to-post TikTok, Reels and Shorts clips. This hosted MCP server lets Claude, ChatGPT, Codex, Cursor and other agents import products, generate clips, fetch download links, browse brand affiliate offers and pitch brands.

• Endpoint: https://app.cartviral.com/mcp (Streamable HTTP, hosted, nothing to install)
• Auth: OAuth 2.1 (dynamic client registration, PKCE) or an API key
• Registry: com.cartviral/cartviral in the official MCP Registry
• Docs: https://cartviral.com/mcp
• Smithery: https://smithery.ai/servers/mercury-promotion/CartViral_mcp
• Price: free account with 18 credits (3 AI clips), no card; read-only tools cost nothing. After your first purchase, the first agent connection adds 20 bonus credits (once per account)
• Clips: photo montages, AI story reels and creator (UGC) clips where an AI creator talks to camera in their own voice, all vertical 9:16 and built from your real product photos

Any other client

Streamable HTTP, URL https://app.cartviral.com/mcp. Either let the client run the OAuth flow (discovery at /.well-known/oauth-protected-resource/mcp), or send Authorization: Bearer YOUR_KEY (or x-api-key: YOUR_KEY). Create keys at https://app.cartviral.com/account/agents.

Tools

Every tool declares readOnlyHint, destructiveHint and openWorldHint.

Example prompts

• "Import https://yourstore.com and show me the 5 products with the best CartViral score."
• "Make 3 AI story clips of the top product and give me the download links when they're ready."
• "Find CartViral Earn offers that ship to the US with at least 20% commission and join the best one."
• "Pitch these Shopify brands: [links]. Tomorrow, tell me which ones opened the page."

Security

• OAuth tokens are opaque and stored hashed; access tokens last 1 hour, refresh tokens rotate on every use. Disconnect any app in Account → AI agents.
• A token or key acts as your account (same credits and limits as the web app). Up to 120 calls per minute per key.
• Agents never post to social media for you: they make and fetch clips, you post.
