1c-rest-mcp

Connects Claude to 1C Enterprise ERP systems via OData 3.0 REST API, exposing nine tools for reading and writing catalogs, documents, and registers. You can query entities with standard OData operators like $filter and $orderby, create and update documents via POST and PATCH, pull reports from HTTP services, and search documents by number. Includes skill wrappers for common patterns like catalog lookups and date-filtered document queries. Primarily targets Russian market 1C deployments. Configure with your 1C server URL and credentials, optionally limit exposed tools via ONEC_SERVICES to reduce LLM context. Ships with both stdio and HTTP transports, the latter exposing POST /mcp for streamable requests.
