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

1. API key auth. Your youfiliate_sk_... key authenticates the MCP server.

2. JWT bridge. The server exchanges your API key for short-lived JWTs against the Youfiliate API.

3. Token caching. JWTs are cached in memory and auto-refreshed.

4. Scoped data access. The server only sees data belonging to the API key's owner.

5. 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

Environment Variables

Development

git clone https://github.com/andrewmpierce/youfiliate-mcp.git
cd youfiliate-mcp
pip install -e ".[dev]"
pytest -v

Test with MCP Inspector

npx @modelcontextprotocol/inspector youfiliate-mcp

Docker

docker build -t youfiliate-mcp .
docker run -p 8080:8080 \
  -e YOUFILIATE_API_KEY=youfiliate_sk_... \
  youfiliate-mcp

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.
