Can I check the open rate for a specific email using the agent?

Yes! Use the `get_email_analytics` tool with the Email ID. Your agent will fetch the detailed statistics, including deliveries, opens, and clicks, directly from Buttondown.

How do I add a new subscriber with a specific tag?

Simply ask the agent to `create_subscriber` and provide the email address and a JSON array of tags, for example: `["customer", "api-lead"]`. The subscriber will be added to Buttondown instantly.

Does the integration allow creating a new draft email?

Yes. Use the `create_email` action and set the status to `draft`. You can provide the subject and the body in markdown format, and it will appear in your Buttondown account ready for review.

Buttondown + Cursor FAQ

Common questions about integrating Buttondown 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.
