Helios Nephrite MCP
Talk to Helios Nephrite. Answers from sales, stock, projects and finance — right in Claude, ChatGPT or Copilot.
No exports, no clicking through reports. You ask — the AI finds the answer directly in your ERP.
What is MCP?
Model Context Protocol is an open standard that lets AI assistants securely access business data and tools. It was created by Anthropic (Claude) and is supported by OpenAI (ChatGPT) and Microsoft. Our MCP server translates AI requests into safe, audited queries against your ERP.
What the AI can do with your system
Write actions are part of the Read + write tier, go through the vendor’s official interface and each one is confirmed by a human.
Production
- Production order progress Plan vs. actual: finished pieces, scrap and hours worked.
- Late production orders Orders past their due date and the operations they are stuck on.
- Costing vs. actual costs Planned vs. actual costs by product and job.
- Work centre load Scheduled work and free capacity of work centres from the production plan.
Sales and stock
- Customer orders Order fulfilment status and what is holding up dispatch.
- Stock levels Stock of materials and finished goods, items below minimum.
Finance and controlling
- Overdue invoices Receivables and payables past due, with amounts and age.
- Results by cost centre Costs and revenue by cost centre and job against plan.
CRM
- Opportunities Open opportunities, their value and next step.
- Customer history Orders, invoices and activities for a customer.
Write (Read + write tier)
- CRM activity A task or meeting is created from the conversation, after you confirm.
- New contact Creates a contact from the conversation details, after you confirm.
Try these prompts
Owner / CEO
- “What were the actual costs of the Alfa Metal job compared with the costing?”
- “Which cost centre is furthest behind plan this year?”
- “How much scrap did we produce in September and at which operations?”
Sales
- “Which orders won’t be dispatched by the end of the month, and why?”
- “Which open opportunities are worth over CZK 1 million?”
- “What has customer Beta ordered this year and how do they pay?”
Accountant
- “Which invoices from material suppliers are overdue?”
- “Break down Q3 costs by cost centre.”
The AI sees only what you allow
Designed for accounting data: trust first, convenience second. Read-only by default, writes only with human confirmation.
We read, we don’t interfere
The service accesses the Helios Nephrite database through a dedicated read-only account — it never writes to the system and doesn’t affect its operation.
Writes only via official interfaces
Write actions go through the vendor’s official interface and every one is confirmed by a human.
Module-level permissions + audit
Payroll and other sensitive modules can be excluded; every request is logged.
Hosted in the EU, encrypted end to end
The cloud service runs in the EU and connects to your database over an encrypted link — via IP whitelisting or your VPN. Beyond the audit log, your data is never stored — and never used to train AI models.
OAuth 2.0, no shared keys
Every user signs in as themselves and access can be revoked at any time.
What you need
- HELIOS Nephrite Enterprise installations differ, so we design the connection after a short review of your environment — reading from the database or through the Nephrite platform’s REST API services.
- Approved database access Whitelisting our IP addresses, or access via your VPN — we agree the details with your IT. Nothing is installed on your side.
- AI account Claude (we recommend Pro or Team) or ChatGPT Business or Enterprise. Microsoft Copilot support is coming.

FAQ
Will it slow our system down?
Queries are optimised for reading and run at low priority; a typical request is a fraction of the load of a standard report. We set limits during deployment.
We run multiple companies (entities).
Yes — the connector supports multiple companies. You either name the company in your question or pin it in the permissions. See pricing for per-company billing.
We are a manufacturer with complex production engineering.
Helios Nephrite MCP reads production orders, bills of materials, costings and production records. You ask about progress, delays or costs; production engineering data is read only and never changed.
Will the AI see all our data?
Only what you allow. Access is configured per module and the default mode is read-only. Sensitive areas (e.g. payroll) can be excluded entirely.
Do I need a paid Claude or ChatGPT subscription?
For day-to-day use, yes. For Claude we recommend Pro or Team (Free allows one custom connector); in ChatGPT, custom MCP servers are available on the Business, Enterprise and Edu plans. You pay the AI provider directly; we’ll help you choose.
Where is my data processed, and what about GDPR?
The service runs in EU data centres and connects to your system securely. Data is never used to train AI models. We sign a data processing agreement (DPA).
Can the AI break anything in the ERP?
Not in Read mode — it never writes to the system. Write actions (higher tier) go through the vendor’s official interface and each one must be confirmed by a human.
What if I upgrade my ERP to a new version?
We track supported versions and keep the connector updated. Let us know before a major upgrade and we’ll verify compatibility in advance.
Are you a partner of the ERP vendors?
No — we are an independent vendor. All ERP names are trademarks of their respective owners. We are in talks with several vendors about partnerships.
