OpenShopGraph for AI tools: MCP in one minute
How to connect Claude, ChatGPT or Perplexity to the shop graph via MCP.
OpenShopGraph speaks two protocols against the same data base: a REST tool API and MCP. The read-only tools — and the MCP tool list itself — are available without a key; they're rate-limited per IP and respond with HTTP 429 and Retry-After when exceeded. Write calls (report_code) still require a key.
Endpoints
Backed with data today are find_shop, list_coupons, get_trust and list_shipping_options as POST /tool/<name>, plus GET /suggest for typeahead. The product and pricing tools (find_product, get_product, compare_prices, price_analytics) exist in the API but currently return no results, because the product catalog isn't populated yet. The full specification is available as OpenAPI 3 at api.openshopgraph.com/openapi.json.
