Debug Webhooks with Cursor Agent

The `list_webhooks` tool allows Cursor to pull your configured endpoints directly into your editor while you write event handlers. You never have to guess what URL is currently registered or switch to a dashboard to check your configuration. When you write routing logic for inbound calls, your AI client uses `list_numbers` to fetch the actual phone numbers available in your account. The agent injects the real IDs into your code, meaning your tests run against live data instead of mocked stubs.

Pull Call Logs into Your IDE

Triggering the `list_calls` tool lets Cursor fetch your recent inbound and outbound call history. If you are building a custom CRM dashboard, your agent pulls the real duration and status metrics to help you shape the frontend components. For deeper troubleshooting of a specific interaction, Cursor calls `get_call`. It grabs the exact timestamps, participant details, and associated notes, giving you the raw JSON payload to write accurate parsing functions.

Fetch SMS Data via MCP Server

You can pull real text message threads into your workspace using the `list_messages` tool. Cursor grabs the message content, sender IDs, and delivery statuses to help you build reliable SMS webhook processors. To map those messages to internal staff, the agent runs `list_users`. It fetches the list of users in your organization, letting you write accurate assignment logic without leaving your code editor.

Setup guide

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

.cursor/mcp.json

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

Common questions about JustCall MCP in Cursor

Create a .cursor/mcp.json file in your project root. Add the server details there, and Cursor automatically loads the tools into your Agent chat.

Yes. When you ask it to build a dashboard, it pulls actual call logs and contacts. It uses those real JSON structures to generate your TypeScript interfaces.

You must enable Agent mode. Regular chat cannot execute external tools, so you need the agent to actually trigger the API requests.

No. The available operations are strictly read-only. You can fetch campaign data, but you cannot launch new dialer campaigns.

Your SMS contents and delivery statuses are fetched directly into your local editor memory. The protocol ensures this data stays between your machine and the API without passing through third-party logging servers.
