Clickwise Affiliate Network MCP server

Clickwise API: products by GTIN, tracked affiliate links, MCP

Clickwise is an affiliate network with an API built for developers and AI agents. Search 1.1M+ products by GTIN across 7 markets, get product links tracked to you, find and join affiliate programs, and pull your conversions. Use it over REST, from an AI agent through MCP, or from HasOffers-compatible tools.

This repo gets you from zero to a working call in under five minutes: quickstarts, thin clients, MCP configs and a deployable affiliate store.

1. First call, no key (60 seconds)

# How big is the catalog right now?
curl -s https://partners.clickwise.net/api/v1/public/catalog-stats/

# Sample products in one market (DE, ES, GB, PT, SE, FR, US); no links without a key
curl -s "https://partners.clickwise.net/api/v1/public/catalog-sample/?country=DE"

# Ask the MCP server which programs fit your site
curl -s https://partners.clickwise.net/api/v1/mcp \
  -H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"find_affiliate_programs","arguments":{"topic":"sneakers","country":"ES","channel":"site"}}}'

2. Get your key

Request a publisher API key at ****. Put it in an environment variable and keep it on your server:

export CLICKWISE_API_KEY=...   # never commit it, never ship it to a browser

3. First call with your key

# Who am I, what can this key do, what are my limits?
curl -s https://partners.clickwise.net/api/v1/publisher/me/ -H "X-API-Key: $CLICKWISE_API_KEY"

# Fresh price, stock and YOUR tracked link for up to 100 GTINs
curl -s --get https://partners.clickwise.net/api/v1/publisher/products/lookup/ \
  -H "X-API-Key: $CLICKWISE_API_KEY" \
  --data-urlencode 'gtins=4006381333931,5901234123457' --data-urlencode 'country=DE'

# Search by title in one market
curl -s --get https://partners.clickwise.net/api/v1/publisher/products/ \
  -H "X-API-Key: $CLICKWISE_API_KEY" \
  --data-urlencode 'q=running shoes' --data-urlencode 'country=ES' --data-urlencode 'limit=20'

Each product comes back as {"gtin", "title", "price", "currency", "image", "url", "merchant", "availability", ...}. url is your tracked link: publish it exactly as returned.

Runnable versions of steps 1 and 3: quickstart/curl.sh · quickstart/quickstart.mjs (Node 18+) · quickstart/quickstart.py (Python 3.8+). No dependencies.

4. Use it from an AI agent (MCP)

Remote MCP server (Streamable HTTP): https://partners.clickwise.net/api/v1/mcp, listed in the official MCP Registry as net.clickwise/mcp. 19 tools; the key is optional (program discovery, deals, catalog stats and instant tracked links work without it).

claude mcp add --transport http clickwise https://partners.clickwise.net/api/v1/mcp --header "X-API-Key: $CLICKWISE_API_KEY"

Configs for Claude Code, Cursor, Claude Desktop and VS Code, plus the tool list, in mcp/.

5. Ship an affiliate store

templates/affiliate-store: a Next.js storefront that reads products by GTIN, shows live prices and publishes your tracked links. It deploys without a key in preview mode.
