What do the statuses 'clean' and 'dirty' mean?

'Clean' means the email address is valid and safe to send. 'Dirty' means the email is invalid, non-existent, or highly likely to bounce.

How many emails can I verify at once?

The `verify_batch_emails` tool supports JSON arrays. It is recommended to keep batches under 3,000 emails per request for optimal performance.

Where do I find my API Key?

Log in to your Listclean dashboard and navigate to Account Settings or Profile to find your unique X-Auth-Token.

Listclean + Cursor FAQ

Common questions about integrating Listclean MCP Server with Cursor.

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.
