AI product Open source
NorthCinder is an open-source, local-first MCP server for AI shopping agents. It compares products from user-selected sources against a buyer's criteria, explains rankings and exclusions, shows source facts and unverified details, and normally returns up to three useful options rather than claiming one universal best product.
Its research workflow provides separate product and seller guides, creates a research plan, and uses controlled research tools; results remain provisional when sources conflict or do not identify the exact item or seller. Purchasing is a separate human-in-the-loop decision: each checkout requires fresh approval for one exact offer and unit, with the merchant, variant, price, known total, and spending cap signed into a single-use approval. It rejects raw card details, using an opaque payment token for supported automated checkout or handing the buyer a cart link.
NorthCinder runs alongside an MCP-capable AI application. Its local setup requires Node.js 20 or later; the init command stores configuration locally and starts the MCP server and search engine in one process. The repository states that there is no hosted NorthCinder account or cloud service, and that order outcomes remain local.
