Test CallFire Endpoints Inside Cursor

The CallFire MCP Server replaces fake API responses with live execution inside your editor. You tell Cursor's Agent mode to write a text-sending function, and it actually fires `send_sms` to verify the payload structure. You know the code works because it just executed successfully. The AI generates code based on real data, not outdated API docs. It runs `get_sms_details` on the message it just sent, looks at the JSON response, and writes the exact parsing logic your application needs.

Audit Voice and Campaign Assets via MCP Server

Hardcoding audio file IDs is a fast way to break your dialer application. Cursor pulls your live assets using `list_campaign_sounds` and inserts the correct identifiers directly into your script. You never have to guess if a sound file still exists. The same goes for your rented phone numbers. The agent checks `list_keywords` to see what you actually own, then populates your environment variables or config files with valid data.

Debug Webhooks and Account Limits

Troubleshooting failed callbacks usually involves digging through third-party dashboards. Now you just ask your editor. The MCP Server runs `list_webhooks` to see exactly where CallFire is sending your delivery receipts. If your tests start failing unexpectedly, the AI can check your balance. It hits `get_account_info` to see if you ran out of credits, saving you an hour of pointless code debugging.

Setup guide

Set up CallFire 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 CallFire 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 CallFire transactions." If the MCP tools are loaded correctly, Cursor will call the CallFire tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "callfire-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about CallFire MCP in Cursor

Create a `.cursor/mcp.json` file in your project root and add the Vinkius server URL. Toggle Agent mode on in the chat panel to start testing endpoints.

Yes, if you ask it to test the integration. The agent executes the tools exactly as instructed, meaning it will trigger live texts and deduct from your account balance.

The agent accesses your past outbound dials using the listing tools. It pulls down recent transactions to help you write accurate data models for your application.

Usually, saving the JSON file triggers a reload of the available tools. If the hammer icon doesn't show the new endpoints, reload the window using the command palette.

The Vinkius architecture isolates your CallFire credentials in a secure, ephemeral sandbox. When Cursor requests a message dispatch, the exact text content and recipient phone numbers exist only during the execution window before being wiped entirely.
