How to Use the Fax.Plus MCP in Cursor

Q: How do I configure Fax.Plus with my Cursor editor?

Create a .cursor/mcp.json file in your project root and add the MCP server definition. Once saved, Cursor's AI agent can call the telephony tools during your coding sessions.

Q: Can I use Cursor to debug Fax.Plus API responses?

Yes, you can ask the editor to run getfaxdetails on a specific ID. The agent will pull the raw transmission logs and show you the exact error codes or delivery confirmations.

Q: Does Fax.Plus work with Cursor's Agent mode?

Absolutely, the agent mode can execute the listfaxes tool over this MCP integration to fetch your communication history. It then uses that data to write or refine your local data-processing scripts.

Q: How do I check my account status in Cursor?

Ask the editor's chat to run getaccountinfo. It will display your current billing plan and active identity details directly in the side panel.

Generate code that interacts with real phone networks and send faxes directly from your Cursor editor during development.

Perplexity

Test outbound faxing without leaving Cursor

The `send_fax` tool transmits digital documents to target numbers directly from your workspace. Cursor's agent mode calls this tool to verify your document pipelines with real network transmissions instead of mocked APIs. You can write a script, run it, and immediately check if the file went through using this MCP connection. Your editor handles the payload delivery, letting you debug transmission errors right inside your workspace.

Build real-time queue monitors in Cursor

The `list_outbox_jobs` tool monitors active transmissions while `cancel_outbox_job` kills pending jobs before they complete. This MCP Server lets Cursor read these live queues directly to help you write accurate status-checking logic. If a job gets stuck, tell the agent to abort it. You see the immediate state change in your editor, which makes developing queue-management systems incredibly fast.

Query live telephone inventory with this MCP Server

The `search_available_numbers` tool finds new inbound lines while `list_fax_numbers` lists your active inventory. Cursor uses this live data to populate your configuration files with real, active phone numbers. Stop hardcoding dummy values in your local environment. This setup pulls actual telephony metadata directly into your active files, ensuring your integration works perfectly before you commit code.

Setup guide

Set up Fax.Plus MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Fax.Plus MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Fax.Plus transactions." If the MCP tools are loaded correctly, Cursor will call the Fax.Plus tools automatically. You can also check Settings → MCP for a green status indicator.
