Extension Ecosystem

Build once.
Ship everywhere.

A first-class SDK that makes building IDE extensions as easy as writing a JSON file and a single TypeScript module.

01
Define the manifest

Declare your extension's ID, permissions, and contribution points in manifest.json.

02
Write the logic

Use the Extension API to register commands, menu items, views, and language providers.

03
Test in sandbox

Run msce dev to launch a live-reload sandbox session inside the IDE.

04
Publish

A single msce publish command bundles, signs, and uploads to the Mono Extension Registry.

manifest.json
{
  "id": "mono-ai-chat",
  "main": "out/extension.js",
  "contributes": {
    "themes": "./config/mono-theme.json",
    "snippets": "./data/ai-snippets.json",
    "commands": [
      {
        "id": "openai.explainCode",
        "title": "AI: Explain Code"
      }
    ],
    "menus": "./menus/context.json"
  }
}
