This is third-party code. Review the repository files before installing.

What it does

The server connects to seller accounts on three marketplaces and reduces their incompatible product, stock and order models to one normalized zod schema, so an agent asks one question and gets one response shape across every connected account. Version v0.3 covers read only: 17 tools, 12 of them data tools validated against an outputSchema. Credentials are stored AES-256-GCM encrypted in PostgreSQL, or passed as environment variables in demo mode with mock data and no keys needed. Each marketplace has its own rate limiter, a shared error model with a retryable flag, and a tool-call audit log.

Who it is for. For sellers on several marketplaces who need one unified view of stock, prices and orders instead of manually comparing three seller accounts.

Example request

Check Wildberries, Ozon and Yandex Market for products with fewer than ten units left in stock

Limitations

Functionality is read-only for now; write with confirmation and stock-history collectors are planned but not built. The Ozon contract was assembled from documentation and community clients since Ozon publishes no official OpenAPI spec, and the author calls this the weakest link. Yandex Market has no separate test environment, only test orders inside the live account. Production needs your own PostgreSQL and a TLS reverse proxy in front of /mcp.

How to disable. Stop the containers with docker compose down or remove the marketplace server from your MCP client config.

MCP

Transport

stdio, http

Authentication

API key

Security check

• Reads private seller data: stock, prices and orders across three accounts
• v0.3 does not write data, but keys live on the server, so keep MCP_AUTH_TOKEN and a TLS proxy in front of a production instance

README in short

The README explains why a single schema sits on top of three incompatible APIs, shows sample npm test output merging stock from three accounts, gives quick starts both keyless and with real tokens, a table of each platform's auth method and test environment, the list of 17 tools, the adapter architecture, and notes on verifying API paths and limits against official specs as of August 28, 2026. It separately covers transport security: a bearer token, Origin validation, and binding to 127.0.0.1 when MCP_AUTH_TOKEN is not set.
