What is the isvat MCP Server?
Empower your AI agent to orchestrate your entire European VAT validation workflow with isvat, the simple and fast API for tax ID verification.

Whether you are conducting financial due diligence or managing international invoicing, your agent acts as a real-time compliance assistant, ensuring your tax data is always verified.

Frequently asked questions
Is an API Key required for isvat?
No. isvat is a free and public service. This server works out of the box without any static credentials required.
Which countries are supported?
isvat supports VAT validation for all countries within the European Union (EU).
Does the agent retrieve company addresses?
The isvat API primarily returns a boolean validation status. For detailed company metadata, including names and addresses, consider using the VATNode or BrasilAPI servers.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
