# Your AI assistant names the standard number and whether it is valid

Your Copilot agent could name a standard's title, but neither its number nor whether it is still valid. That is one of the first questions engineering firms put to a standards library. The MCP interface now returns, in search hits and publication details, the identifiers you recorded without an ISBN or DOI, such as the standard number `DIN 1045-1:2008-08` or an internal shelfmark.

For a standard, `get_publication` also returns the status (`active` or `withdrawn`), the kind (normal, draft, amendment or other), and its predecessors and successors. Asked "Is DIN 14230 still valid?", the agent answers from your holdings and, for a withdrawn standard, names what replaced it. The status is the one you recorded in Librario; Librario does not check it against the DIN catalogue.

More about the connection is in the [MCP documentation](/en/docs/integration/mcp).
