# Kong Reviews

> Kong Reviews answers two questions for anyone who wants to build something: what do I use to build this, and how much will it cost? For example: an app that tracks the beans in my pantry. It says what to build it with (an AI app builder or coding agent), which developer services to use, how to set them up, and what they cost now and as you grow, with the startup credits that apply. Works for a new product or a feature for an app that already exists. Every price is read from the vendor's own pricing page and carries the date it was checked.

Use it from an AI app over MCP with a free Kong Reviews account: add the remote MCP server https://kongreviews.com/mcp (Streamable HTTP) to Claude, ChatGPT, Cursor or VS Code, and the app opens the sign-in (OAuth) when it connects. Useful tools: recommend_stack (describe a product or feature, get a priced plan), get_project_context (continue a saved project), price_change and accept_change (price a change against the plan before building it, then keep it), get_build_pack and record_setup_progress (set it up step by step), explain_bill (bills against the estimate), compare_architectures (a short interview, then the top three architectures and why the others were ruled out), detect_stack (what an existing app runs on, from its files, repo or site), evaluate_change (stay, optimise or switch when a feature such as SSO is needed), audit_stack, estimate_cost, compare_vendors, find_perks, search_directory and search_showcase. Answers cite their sources and dates.
