FAQ

Frequently asked questions

How do I submit multiple emails for validation at once?

Use the validate_bulk tool and provide an array of email addresses in the emailList parameter. The server will return a trackingId which you can use to check the results.

How can I check if my bulk validation task is finished?

You can use the get_validation_status tool by providing the trackingId received during the submission. It will return the current progress or the final validation results.

Is there a way to prevent sending the same validation request twice?

Yes, when using validate_bulk, you can provide an optional hashkey. This unique string prevents duplicate requests from being processed within a 3-minute window.

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.
