# CartLens > Cart & lost-sales analytics for OpoShop stores — see the exact abandoned carts (products, value, the step each shopper left at), an honest funnel with the leaks named, per-visitor journeys, a product leak leaderboard, and a live-visitor pulse. This app is built on the OpoShop platform. It is agent-friendly: the full API is described in OpenAPI and wrapped by an MCP server so an LLM can drive it directly. ## Machine interfaces - API contract (OpenAPI): https://app.trycartlens.com/openapi.json - API docs (Swagger): https://app.trycartlens.com/docs - Fuller LLM context: https://app.trycartlens.com/llms-full.txt - Release notes: https://app.trycartlens.com/api/release-notes - MCP endpoint (hosted): https://app.trycartlens.com/mcp — add this URL to Claude or any LLM client to drive the app in natural language.
