1C OData MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 35 installs a week from npm. Last commit 7 Aug 2026.
Read-only MCP server for 1C:Enterprise via OData with metadata and query builder tools.
Today is the operative word: we check 1C OData MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
ONEC_BASE_URL (1C OData endpoint URL (e.g. https://host/db/odata/standard.odata)), ONEC_USERNAME (Basic auth username for the OData endpoint), ONEC_PASSWORD (Basic auth password for the OData endpoint), ONEC_DATABASE (Optional database name hint), ONEC_METADATA_CACHE_TTL_MS (Metadata cache TTL in milliseconds (default 3600000)), ONEC_CONFIG_PATH (Optional path to JSON config file ({ baseUrl, username, password })).
The author declared them in the registry entry; get the values from the project itself.
