Make it yours, then make it do more

Install extensions for your languages, frameworks, and tools. Connect agents to outside systems with MCP servers, add more models, or install a complete agent setup as a plugin. If the tool you need does not exist, build it with the Extension API and share it publicly or with your team.

Why extend VS Code

Adapt every part of your setup, from languages to AI, and share what you build with your team.

Fit VS Code to your workflow

Install extensions for any language, framework, or tool, then layer on themes and profiles to match how you like to work.

Extend AI with your own tools and models

Connect MCP servers, add model provider extensions, and install agent plugins to give agents new capabilities and context.

Build what's missing

Use the Extension API to create language servers, debuggers, custom editors, and views, anything the marketplace doesn't already offer.

Share and control what runs

Publish extensions and plugins publicly, or host a private marketplace to distribute internal tools across your organization.

And much more

Keyboard shortcuts

Remap every command, install keymap extensions for Vim or Emacs, and export a printable shortcut reference.

Settings

Fine-tune every behavior with user, workspace, and folder-level settings, through the UI or directly in JSON.

Themes

Change color and icon themes to match your style, or install one from the marketplace.

Snippets

Create reusable code templates with tab stops and variables, or install snippet packs from the marketplace.

Profiles

Bundle settings, extensions, keybindings, and snippets into switchable profiles, one for each project or language.

Language Server Protocol

Build a language server once and it works in VS Code and any LSP-compatible editor, written in any language.
