Youfiliate MCP Server

<!-- mcp-name: io.github.andrewmpierce/youfiliate-mcp -->

MCP (Model Context Protocol) server for managing Youfiliate Smart Links from AI assistants like Claude Desktop. Create geo-targeted affiliate links, view analytics, and run YouTube description migrations — all from a chat conversation.

18 tools, 4 resources, supports stdio + streamable HTTP transports.

Installation

pip install youfiliate-mcp

Requires Python 3.11+ and a Youfiliate account.

Generate an API key

1. Log in at youfiliate.com
2. Go to Settings → API Keys
3. Click Create API Key (e.g. "Claude Desktop")
4. Copy the key (starts with youfiliate_sk_) — shown only once

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?

> 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

| Variable | Default | Description |
|----------|---------|-------------|
| YOUFILIATE_API_KEY | (required) | Your API key |
| YOUFILIATE_API_BASE_URL | https://app.youfiliate.com | Backend URL |
| MCP_SERVER_SECRET | (empty) | Shared secret for verify-api-key (server operators only) |
| TRANSPORT | stdio | stdio or streamable-http |
| PORT | 8080 | Port for HTTP transport |
| HOST | 127.0.0.1 | Bind address (use 0.0.0.0 in Docker) |

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.
