How do I find my Mailshake API Key?

Log in to Mailshake, navigate to 'Extensions' in the main menu, and select 'API' to generate or copy your personal API key.

What is the difference between a Lead and a Recipient?

A Recipient is anyone added to a campaign. A Lead is a recipient who has met specific engagement criteria (like replying) and is tracked in the 'Lead Catcher'.

Can I add multiple prospects at once?

Yes, the `add_prospects_to_campaign` tool accepts a JSON body where you can provide a list of multiple recipients to be added in a single request.

Mailshake + Cursor FAQ

Common questions about integrating Mailshake 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.
