How do I find my SignalWire Project ID and Token?

Log in to your [**SignalWire Dashboard**](https://signalwire.com/signin), select your Project, and navigate to **API** in the sidebar. You will find your Project ID and can generate a new API Token there.

What is the Space URL?

The Space URL is the prefix of your SignalWire domain (e.g., if your domain is `example.signalwire.com`, the Space is `example`). Enter only the prefix.

Can the agent send SMS messages?

Yes. Use the `send_sms` tool providing the recipient number, your SignalWire number, and the message body. Your agent will deliver the SMS and confirm the status instantly.

SignalWire + Cursor FAQ

Common questions about integrating SignalWire 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.
