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.

An extension for everything

Add language support, debuggers, linters, and entire toolkits from thousands of extensions built by Microsoft and the community, all installable with a single click.

Give agents access to your tools and data

Install MCP servers from the marketplace to connect agents to your databases, browsers, issue trackers, and APIs, so they can act on real systems, not just code.

Discover and share agent plugins

Agent plugins bundle instructions, skills, custom agents, hooks, and MCP servers into one installable package. Browse the default marketplaces, or add your own, including a private one for your team.
