Example Conversations
Creating a Smart Link
You: Create a smart link for https://amazon.com/dp/B09V3KXJPB with geo-targeting for UK and Germany.
Claude: (calls youfiliate_create_smart_link with geo rules for GB and DE)
Done. Short URL: youfil.to/b09v3kxjpb
- US (default): amazon.com/dp/B09V3KXJPB
- UK: amazon.co.uk/dp/B09V3KXJPB
- Germany: amazon.de/dp/B09V3KXJPB
Checking Analytics
You: How are my links performing this month?
Claude: (calls youfiliate_get_aggregate_stats with period="30d")
1,234 clicks. Top countries: US (500), UK (200), Germany (150). Most traffic from YouTube (900 clicks).
YouTube Migration
You: Convert all my YouTube description links to smart links.
Claude: (calls youfiliate_preview_migration) Would affect 15 videos / 42 links. Proceed?
You: Yes.
Claude: (calls youfiliate_start_migration with confirm=True)
Security Model
- API key auth. Your
youfiliate_sk_... key authenticates the MCP server.
- JWT bridge. The server exchanges your API key for short-lived JWTs against the Youfiliate API.
- Token caching. JWTs are cached in memory and auto-refreshed.
- Scoped data access. The server only sees data belonging to the API key's owner.
- Destructive actions guarded. Delete, disconnect, start migration, and rollback require explicit
confirm=True.
Rate Limits
- MCP layer: 60 requests/minute per API key
- Health checks: 1 per link per 5 minutes
- API key exchange: rate-limited by the Youfiliate backend

Troubleshooting
"Authentication failed" — verify your API key, regenerate at youfiliate.com/settings if needed.
"Could not connect to the Youfiliate API" — check YOUFILIATE_API_BASE_URL. Defaults to https://app.youfiliate.com.
"Rate limit exceeded" — wait a moment. Health checks are 1 per 5 minutes per link.
Tools not appearing in Claude Desktop — check claude_desktop_config.json syntax, restart Claude Desktop, run youfiliate-mcp --help to verify the binary is on your PATH.
