# Mercur Documentation
> The open-source enterprise marketplace platform. Composable, API-first, and AI-native, on infrastructure you own.
Mercur is the open-source enterprise marketplace platform. It gives operators
multi-vendor governance: sellers, offers, commissions, order splitting, and
payouts, with role-based access and an auditable change pipeline, on
infrastructure you own. Core commerce runs on the proven Medusa engine, so
products, pricing, carts, orders, and payments are mature from day one.
## Get started
Install Mercur, tour the panels, and watch a multi-vendor order flow.
Governance, ownership, and composability without a closed platform.
How the marketplace platform is architected, module by module.
Version-matched docs, agent skills, and the MCP server.
## Explore the platform
Each marketplace capability is its own module, with concepts, server guides, and a
data-model reference.
Govern who sells, with role-based access and an account lifecycle.
One shared master catalog that every store sells against.
A seller's listing against a master product, with its own price and stock.
A typed attribute catalog that also drives variant axes.
The auditable change pipeline behind every catalog edit.
How a single cart splits into per-seller orders.
Policy-based rules and per-order commission lines.
