How do I find my Kit API Secret?

Log in to Kit, go to **Settings > Advanced**. Under 'API', click **Show** next to API Secret, copy the string, and paste it below.

Why is the API Secret required instead of the standard API Key?

The API Key only provides read access to public forms. The API Secret grants full access to manage subscribers, tags, and broadcast data as needed by this integration.

Can the agent send broadcast emails?

No. For safety, the integration is read/manage only. The agent can check campaign metrics and manage tags, but actual email sending must be done via the Kit dashboard.

Kit (ConvertKit) + Cursor FAQ

Common questions about integrating Kit (ConvertKit) 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.
