What’s New in GitHub Copilot for VS Code v1.109?



On February 4, 2026, GitHub officially announced the January release of GitHub Copilot for Visual Studio Code v1.109. This update goes far beyond simple bug fixes—it's a major upgrade that shifts the paradigm of AI coding assistants from "autocomplete tools" to "autonomous agent collaborators." Key highlights include support for Anthropic’s Claude Agent SDK, MCP (Model Context Protocol) integration, and enhanced multi-agent session management.

Key Update 1: Claude Agent Support (Public Preview)

The most notable change in this release is the integration of the Claude Agent SDK into VS Code. GitHub Copilot Pro+ and Enterprise subscribers can now directly leverage Anthropic’s powerful Claude agent capabilities within VS Code.

  • Public Preview of Claude Agent SDK: Delegate tasks using Anthropic’s official Claude Agent SDK
  • Deduct usage from your existing GitHub Copilot subscription’s Claude model quota
  • Enable agents to autonomously handle long-running, multi-step coding tasks
  • Build automated pipelines: code generation → test writing → PR description drafting

This seamlessly embeds Claude’s industry-leading coding performance (SWE-bench 74.2%, #1 on LM Arena coding leaderboard) directly into the Copilot workflow inside your IDE.

Key Update 2: MCP (Model Context Protocol) App Integration

v1.109 enables richer chat interactions via MCP (Model Context Protocol). MCP is an open standard that allows AI agents to communicate with external tools and data sources. With this update, GitHub Copilot in VS Code can now directly connect to a wide range of external systems.

  • Direct access to databases, APIs, and file systems via MCP servers
  • View tool execution results inline within the chat interface
  • Tap into hundreds of existing MCP ecosystem integrations directly from VS Code

Key Update 3: Multi-Agent Development and Session Management

Complex tasks can now be distributed across multiple agents with official support for multi-agent development workflows.

  • Improved Agent Session Management: Track and manage multiple agent tasks simultaneously
  • Enhanced behavior: agents now ask clarifying questions instead of making assumptions when stuck
  • Visualize Thinking Tokens to transparently observe the agent’s reasoning process
  • Save session history and reuse previous task contexts

Key Update 4: Full Copilot Chat UX Overhaul

Several user experience improvements have been introduced:

  • Improved Streaming Responsiveness: Faster, smoother chat interactions
  • Better Reasoning Quality: More reliable responses and task execution
  • Redesigned Editor Inline Chat: Smoother, context-aware Copilot interactions in-code
  • Enhanced Agent Security & Trust: Explicit control over what actions agents can perform

Agent Customization: Build Your Own Copilot Agent

With v1.109, agent customization capabilities have expanded. You can now fine-tune your Copilot agent’s behavior for specific teams or projects:

  • Train on project-specific coding conventions and style guides
  • Set preferences for internal APIs and libraries
  • Save and share team-specific prompt templates

Copilot Pro+ vs Enterprise: Which Plan is Right for You?

Latest agent features—including Claude Agent SDK and MCP integration—are available on Copilot Pro+ and higher. Individual developers should consider Pro+ ($19/month), while teams and enterprises are recommended to go with Enterprise ($39/user/month). As of 2026, GitHub Copilot supports multiple models, including Claude by Anthropic, OpenAI Codex, and GPT-4o.

How to Get Started Right Now

Here’s how to update to the latest version of GitHub Copilot in VS Code:

  1. In VS Code’s Extensions tab, search for "GitHub Copilot Chat" and update
  2. Open Command Palette (Ctrl+Shift+P) → Run "Copilot: Open Agent Mode"
  3. Select Claude or your preferred model from the model dropdown
  4. Make a natural language request in the chat (e.g., "Write unit tests for this function and update the README")
