How do I send an SMS via the agent?

Use the `send_sms` tool and provide the recipient's phone number and the message body. Your agent will process the delivery through ActiveTrail's SMS gateway.

What are the API rate limits for ActiveTrail?

ActiveTrail endpoints limit excessively high request rates. It is recommended to use pagination tools for large datasets and consult the official API documentation for specific constraints.

Can I configure webhooks using the agent?

ActiveTrail refers to webhooks as 'Events'. While you can monitor campaign events, standard webhook setup needs to be done via the ActiveTrail integration settings panel.

ActiveTrail + Cursor FAQ

Common questions about integrating ActiveTrail 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.
