Usage

VS Code with MCP Extension (Recommended)

You can configure the AL-Go MCP server in two ways:

Option 1: User Settings (Recommended)

Add to your User MCP Configuration for access across all projects in the same VS Code profile:

Note: User settings are profile-specific. The server will be available for all projects opened with the same VS Code profile (e.g., "Node.js", "Default", etc.).

1. Open VS Code Command Palette (Ctrl+Shift+P)
2. Run "MCP: Open User Configuration"
3. Add the server configuration:

{
  "servers": {
    "al-go-docs": {
      "type": "stdio",
      "command": "npx",
      "args": ["--yes", "al-go-mcp-server@latest"]
    }
  },
  "inputs": []
}

Option 2: Project Settings

Add to your project's .vscode/mcp.json for project-specific configuration:

{
  "servers": {
    "al-go-docs": {
      "type": "stdio",
      "command": "npx",
      "args": ["--yes", "al-go-mcp-server@latest"]
    }
  }
}

With GitHub Authentication (Recommended)

Provide a GitHub token for higher rate limits, and to enable discussion and issue search:

{
  "servers": {
    "al-go-docs": {
      "type": "stdio",
      "command": "npx",
      "args": ["--yes", "al-go-mcp-server@latest"],
      "env": {
        "GITHUB_TOKEN": "your_github_token_here"
      }
    }
  }
}

Command Line (Advanced)

# If installed globally
al-go-mcp-server

# Or using npx (no installation needed, always latest)
npx --yes al-go-mcp-server@latest
