Perplexity

Cursor MCP Server for live SMS testing.

Writing code for SMS integrations usually means mocking fake responses. This MCP Server changes that. Cursor can use `list_messages` to pull real SMS payloads into your editor while you write the parsing logic. When you need to test outbound flows, Agent mode can execute `send_message` right from your prompt. You see the actual API response and adjust your code immediately.

Pull real call logs into your scripts.

Building a dashboard or custom CRM sync requires accurate data structures. Instead of guessing the JSON format, your AI client runs `list_calls` to fetch real interaction data. If you are debugging a specific failed call sync, Cursor can run `get_call_details` to inspect the exact metadata. It writes the error-handling code based on the actual failure state, not a documentation assumption.

Audit webhooks and team structures.

Managing an automated phone system requires knowing your current setup. The `list_webhooks` tool lets Cursor check your active event subscriptions before writing new webhook handlers. You can also pull down your active numbers using `list_account_numbers` or check staff assignments with `list_team_users`. The AI writes configuration files using your actual account details.

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.
