Learn about integrating an AI agent into Visual Studio Code

In a constantly evolving technological world, the way we develop our software projects is changing rapidly. Integrating artificial intelligence into our development tools has become essential. In 2025, with the release of Visual Studio Code 1.99, developers are invited to take the leap towards an increasingly AI-assisted approach, radically transforming their workflows. This article offers an in-depth look at the new features Microsoft is offering with this essential IDE.

The Revolutionary New Features of Visual Studio Code 1.99

Visual Studio Code, known for its flexibility and wide range of extensions, welcomes a major update that bridges the gap between traditional and AI-driven development. With the integration of an AI agent into Chat Copilot, Microsoft’s strategy is clear: to simplify programming, even for the most complex tasks. The New Agent Mode: Programming Assistance VS Code’s Agent Mode will transform the way developers interact with their development environment. By allowing code to be written using natural language queries, users can request specific actions such as:

Create files for a new project

Run unit tests

Write technical documentation
Run complex commands
To enable this mode, simply access the settings and search for the appropriate option. Once enabled, the system uses a tool called “Thinking,” which allows the AI to perform step-by-step thinking, much like Anthropic does with its Sonnet 3.7 model.
Powerful tools integrated into Agent mode

Agent Mode isn’t just a natural language coding intermediary; it also integrates advanced tools to enhance the developer experience. These include:

Tool

Feature

Fetch Tool	Fetch content from public web pages
Usage Tool	Deep code comprehension via
Find All References	and Go to Definition Terminal Commands Execute terminal commands directly in VS Code
These tools allow developers to request tasks such as: “Create an Express API endpoint with a MongoDB connection.” The agent can then generate all necessary files, install dependencies, and even run unit tests automatically.	New protocol standards with MCP

The VS Code update also introduces the

Model Context Protocol

(MCP), making it easier to integrate AI models with external tools and applications. This means developers can now make their projects interact with other platforms, opening up unprecedented opportunities. Custom API Support for Increased Flexibility Another major advancement in Visual Studio Code 1.99 is support for custom APIs. This means developers can now choose from a range of AI models: Azure OpenAI

Anthropic (Claude)

Google Gemini

OpenAI (Various GPT models)
This flexibility allows businesses to ensure the security and privacy of their projects. For example, by using Ollama for local models, the code never leaves the local development environment, a valuable asset for privacy-conscious businesses. However, if a business has an Azure subscription, it can use it directly without having to rely on standard Microsoft services.
Leveraging the Capabilities of Claude and Other Models
For developers who appreciate Claude’s depth of understanding, integration with the Anthropic API offers more robust interactions compared to GPT-4o. This is an ideal choice for those seeking precision and simplicity in their application development.

General User Experience Improvements in Visual Studio Code

Microsoft hasn’t stopped at Agent functionality alone. The 1.99 update comes with a series of improvements affecting all aspects of the IDE, resulting in new features and optimizations:

Unified Chat View: Unification of Ask, Edit, and Agent modes.

Image Support: Import images directly into chat (supported formats include .jpg, .png, .gif, .webp).

Next Edit Suggestions (NES): Now in final release.

Instant indexing of the codebase, allowing users to receive answers quickly. Semantic searches powered by artificial intelligence are now enabled by default, enabling smarter searches. For example, users can simply ask the AI to “find all functions that manipulate user data without validation,” a task that could take hours without AI assistance.

Unified Chat View

Simplified interaction between different work modes. Image Support Easier graphical communication with chat.

Semantic Search	Facilitates complex searches with simple queries.
These improvements make Visual Studio Code even more attractive to developers, enabling seamless collaboration and increased productivity.	Why choose Visual Studio Code for your development projects?
With all these revised and optimized features, it’s becoming vital to ask yourself the question: why not adopt Visual Studio Code as your primary IDE? Due to its diverse extensions and adaptability, it easily competes with alternatives like JetBrains, Eclipse, or Sublime Text. These other IDEs have their own strengths, but Microsoft’s integrated, AI-assisted approach gives it a unique position in the market.	Integration and Legacy of AI Agents in Development
AI agents are revolutionizing not only the way we develop, but also our vision for the future of software development. With the rise of tools like those integrated into Visual Studio Code, IT is becoming more fluid and accessible. The importance of an agile environment and intelligent assistance is now paramount in the development cycle.	It’s clear that platforms like GitHub are also reinforcing this trend by enabling project and knowledge sharing enriched by artificial intelligence. Thanks to these advances, development is taking a step toward a more intuitive era, where the machine becomes an ally, more than just a tool. Finding yourself facing a screen of code is no longer inevitable! AI agents like those found in Microsoft’s environment are there to support us, and with ongoing updates, this assistance only improves.
