With the NetCero connector, Claude accesses your data in NetCero directly. Ask about emissions, open data points or the results of your materiality assessment and get the answer in the chat, without exporting data. The connector uses the Model Context Protocol (MCP).
Requirements
A NetCero account with access to at least one organization
A Claude account in which you are allowed to add connectors. In Claude Team and Enterprise, your Claude administrator may need to approve this.
Add the connector
Claude (web, desktop, mobile)
In Claude, open Settings and select "Connectors".
Select "Add custom connector" and enter this URL:
https://api.netcero.eu/mcpClick "Connect" and sign in with your NetCero credentials.
Confirm the access. NetCero is then available in every new chat.
Claude Code
Run in your terminal:
claude mcp add --transport http netcero https://api.netcero.eu/mcp
On first use, your browser opens for the NetCero sign-in.
What Claude can do
Claude works with your permissions. You see exactly the organizations and modules in Claude that you see in NetCero, with the same roles.
Organizations in which you only have the auditor role are not reachable through the connector.
Claude can read data and, if your role allows it, change data. By default, Claude asks for your confirmation before each data access. Review changes before you approve them.
Examples
"What were our Scope 1 and Scope 2 emissions in fiscal year 2025?"
"Which ESRS data points are still empty in our organization?"
"Summarize the material impacts, risks and opportunities from our materiality assessment."
Data and privacy
The connector only transfers data that you request. Claude processes this data in your Claude account under Anthropic's terms. Your data processing agreement with NetCero continues to apply to your data in the NetCero platform. More in our privacy policy.
Disconnect
Remove the connector in Claude under "Connectors". Claude then no longer has access to your NetCero account.
