Perplexity

A shared JustCall MCP Server setup.

Solo developers configure tools locally. Engineering teams commit a `.vscode/mcp.json` file to the repository. This ensures everyone using VS Code Copilot has instant access to your telephony data without manual setup. When a new engineer needs to debug a messaging issue, their AI client already knows how to run `list_messages` and `get_message_details`. The team moves faster because the environment is standardized.

Debug call routing and webhooks inline.

Troubleshooting dropped webhooks is tedious. Now, your agent can run `list_webhooks` to verify your endpoint configurations directly from the editor. If a specific call failed to log in your CRM, you can ask Copilot to investigate. It uses `get_call_details` to pull the exact event data, helping you identify the bug in your routing logic immediately.

Manage test accounts and phone numbers.

Writing integration tests requires knowing which numbers are available. The `list_account_numbers` tool pulls your active inventory straight into the chat window. You can also spin up test users. The AI can check existing staff with `list_team_users` or generate fresh test records by calling `create_contact`. You stay in the editor and keep working.

Setup guide

Set up JustCall MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the JustCall MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the JustCall tools listed. Try asking: "List my recent JustCall transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

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

Common questions about JustCall MCP in VS Code Copilot

Add the server configuration to a workspace-level `.vscode/mcp.json` file. Commit it to your repository so every developer inherits the tools.

Yes. Instruct the agent to run the `send_message` tool. It will dispatch the text using your configured API credentials.

You need VS Code version 1.96 or higher to use these features. Older versions lack the necessary protocol support.

Ask your agent to search for the phone number. It will execute `list_contacts` to find the match and `get_contact` to pull the full profile.

Your team's call metadata, SMS payloads, and webhook configurations remain protected. The integration relies on ephemeral, stateless execution, meaning no sensitive customer information is cached or stored by the host platform.
