Frequently asked questions
How do I get my Substack API token?
Log in to your Substack publication at yourdomain.substack.com. Navigate to Settings from the left sidebar. Look for the Publication API or Developer section. Generate an API token and copy it. Paste it into the configuration field below. Note: Substack's API is currently in limited availability — check Substack's developer page for the latest access information.
Can I draft and schedule newsletter posts?
Yes. Your AI agent can create draft posts with title, body content, subtitle, and metadata. You can then schedule them for a specific date and time — managing your entire editorial calendar conversationally.
Can I track how many subscribers I gained this month?
Yes. Ask your AI agent for subscriber growth metrics and get total subscribers, new subscribers this month, churn rate, and free vs. paid subscriber breakdown.
Does this work with paid Substack publications?
Yes. The integration supports both free and paid publications. You can manage paywalled content, check paid subscriber counts, and analyze revenue metrics through your AI agent.
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.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
