Commerce Layer Metrics MCP Server is a local MCP server implementation that provides tools to interact with the Commerce Layer Metrics API for data analysis. It enables extraction and aggregation of metrics from orders, carts and returns within your organization. The server supports four query types—breakdown, date breakdown, stats, and search— across three resources (orders, carts, returns). Breakdowns return computed metrics or statistics on a chosen field, grouped by another field; date breakdowns show date-by-date values over a time interval with an operator applied to a selected field; stats perform numeric computations on a field; searches return actual records with sorting, filtering, and pagination. The repository also describes a library of ready-to-use tools for common business scenarios such as identifying best-selling products by market, customers who bought a specific product, frequently bought together items, and other orders and returns insights. Deployment options include building from source with pnpm, generating a dist folder for a local server, and packaging as a Claude Desktop extension for easy installation and integration with AI agents.
