VS Code

Prerequisites

VS Code with MCP support (VS Code 1.99+)
A MCPCore server with at least one tool
The config snippet from your server’s Integration tab

Step 1 — Get your config snippet

Open your server’s detail page, click the Integration tab, and select VS Code. Copy the generated snippet. VS Code uses a servers key (not mcpServers) and a type: "http" field:

{
  "servers": {
    "your-server-code": {
      "type": "http",
      "url": "https://your-subdomain.mcpcore.io/mcp"
    }
  }
}

For API Key mode:

{
  "servers": {
    "your-server-code": {
      "type": "http",
      "url": "https://your-subdomain.mcpcore.io/mcp",
      "headers": {
        "Authorization": "Bearer <your-api-key>"
      }
    }
  }
}

Step 2 — Add to your workspace config

Create or open .vscode/mcp.json in your workspace root and paste the snippet:

your-project/
└── .vscode/
    └── mcp.json    ← create this file

If you want the server available across all workspaces, add it to your VS Code User Settings instead:

Open Command Palette (Cmd+Shift+P / Ctrl+Shift+P)
Search for Preferences: Open User Settings (JSON)
Add the servers block at the top level

Step 3 — Reload VS Code

Save the config file. VS Code picks up MCP configuration changes automatically — you may need to open a new chat to see the updated tools.

Step 4 — Verify

Open Copilot Chat or Agent mode in VS Code and reference one of your tools. Your MCPCore tools are available in any AI-powered feature.

Troubleshooting

Problem	Solution
Tools not appearing	Ensure VS Code 1.99+ and that the `servers` key (not `mcpServers`) is used
`401 Unauthorized`	Verify the `Authorization` header value
JSON parse error	Validate `.vscode/mcp.json` syntax
Tool calls fail	Check Traffic Logs
