## Services


## Free services

- [The 4chems MCP Server](https://www.4chems.com/mcp/): Connect an AI assistant to the 4chems MCP server — endpoint and transport, authentication, the live customer-tier platform tools (onboarding, catalog, consents, tenant administration), and the planned metadata-only migration check.
- [IUCLID 5 to 6 Conversion](https://www.4chems.com/iuclid-5-to-6/): Convert legacy IUCLID 5 dossier and substance files (.i5z / .i5a) to IUCLID 6 (.i6z) — a free service from 4chems. ECHA provides no standalone converter; we run the real software for you, with batch support, EU-hosted and GDPR-compliant.
- [IUCLID 5 to 6 Conversion for KKDİK](https://www.4chems.com/kkdik/): Türkiye's KKS is aligned to IUCLID 6, so legacy IUCLID 5 files (.i5z / .i5a) cannot be used for a KKDİK registration. 4chems converts them to valid IUCLID 6 (.i6z) for free, EU-hosted and GDPR-compliant. Hosted IUCLID 6 for Only Representatives and KDUs. Also available in Turkish.
