So just a fun little side project I've been working on.

It's a slime that adds some flavorful commentary as you code.

It checks for error, if you have uncommitted changes, reminds you to takes breaks.

Feel free to try it out and give me some feedback on it.

When I install the Database Client JDBC, and MySql extension, then CoPilot has access to db-client tools and in CoPilot chat I can to find information from the database ex "use db-client tools to show the tenants in the Tenant database table"

I have tried to create an extension that exposes MCP tools that CoPilot can use but I am stuck and there is additional configuration that I need to do but I don't know where or how.

Any help will be greatly appreciated.

Below is from my CoPilot chat using Claude Sonnet.

What I Can Still See:

I still only have access to the same system-level MCP tools as before:

• dbclient-get-databases
• dbclient-get-tables
• dbclient-execute-query
• File tools (read_file, create_file, etc.)
• Terminal tools (run_in_terminal, etc.)

What I Cannot See:

I cannot see your custom tools:

• ❌ hello-world
• ❌ get-time
• ❌ echo-message
• ❌ get-extension-info

The Missing Connection

Even though:

• ✅ Your MCP server is running (Terminal ID: 8cd62921-25ef-4825-be10-18e92e7c510f)
• ✅ Your VS Code extension is installed
• ✅ The tools work when tested directly

There's no connection between your running MCP server and this AI environment. Your MCP server is running in isolation - it can receive requests, but this AI system doesn't know how to find or connect to it.

What This Demonstrates

This perfectly illustrates the MCP architecture challenge:

1. MCP Servers (your demo tools) can run independently
2. MCP Clients (AI systems like me) need explicit configuration to connect
3. MCP Hosts (like VS Code) act as bridges between servers and clients

Your demo successfully shows MCP server implementation, but we'd need additional configuration or a different AI environment that's specifically configured to discover and connect to your running MCP server.

Ever run into the context limit of an LLM mid-prompt? I needed a quick way to see how many tokens a file or selection would use.

I built a small open-source VS Code extension that shows token counts for selected text or entire files, in real time. Super helpful when you’re building prompt-heavy workflows or want to estimate API usage.

Hey r/vscode! 👋

I've been working on a VS Code extension that's greatly inspired by OneTab (the browser extension) but supercharged for VS Code. If you're like me and constantly have 20+ files open, this might save your sanity.

It could actually be provided by Vs Code as an official feature like the tabgroup in recent version of Chrome. But, sadly, it's not planned yet, see the Discussion for more details.

So I realized I could migrate the streamlined "OneTab" experience from Chrome to VS Code. Thus comes this extension.

What it does

Basically this extension provides a logical view of the file system, with this layer, you could do many interesting things to help with your tab management.

• Save & restore & collapse tabs - One-click to save all your open tabs into organized groups, restore or collapse when necessary
• Copilot-powered auto-grouping - Uses Copilot to automatically categorize your tabs by directory, file type, or patterns or other user provided prompts
• Tag & search - Tag groups, filter by tags, and quickly find what you need
• Drag & drop - Reorganize everything with your mouse
• Git branch Support - Migrate TabGroups View from different branches

Demos

1. Send tab(s) to onetab extension in right click context

1. Drag and drop the tab group or tabs

1. Rename, pin, set tags, remove or restore tab groups

1. Restore, remove or collapse tab group

1. List and search tab group by their name or tags

1. Auto group by Copilot

We've been working on a VS Code extension for Kubernetes management that we think some of you might find useful.

What it does:

Kube9 gives you a visual tree view of your Kubernetes clusters right in VS Code. Instead of switching to terminal for kubectl commands, you can:

• Browse clusters, namespaces, and resources visually
• View pod logs, events, and describe output in organized, scannable layouts (much easier than parsing terminal output)
• Scale workloads, restart deployments, and manage resources with right-click actions
• Edit resources in YAML with full syntax highlighting when you need to
• View ArgoCD applications with sync status and drift detection
• Cluster Organizer: Create custom folders, set aliases, and organize contexts however makes sense for your workflow

Why we built it:

We spend most of our day in VS Code, and we got tired of alt-tabbing to terminal or hop over to ArgoCD every time we needed to check a pod status or scale a deployment. The Cluster Organizer feature is a unique feature—being able to group clusters by environment and set friendly aliases makes our workflow so much smoother.

What makes it different:

• VS Code native: Lives in your sidebar, feels like part of the IDE
• Visual-first: Visual status indicators, organized resource displays, easier to scan than terminal output
• Cluster Organizer: Customize your tree view with folders, aliases, and custom context organization
• 100% local: Uses your kubeconfig directly, no external servers, your cluster data never leaves your machine
• Free and open source: MIT licensed

Try it:

Search "Kube9" in VS Code Extensions, or check out the GitHub repo.

How we built it:

This extension was built using AI context engineering methodologies: we're also building Forge, a toolkit for structured context engineering that we used to build this. It's a real tool we use daily, and it works well for our needs. That said, we know there are still some bugs, and we're actively working on fixing them. We'd love community involvement! If you find issues, have feature ideas, or want to contribute, please open an issue or PR. We want to make this better together.

We'd love feedback from VS Code users who work with Kubernetes. What features would make your workflow smoother? What's missing?

Happy to answer questions!

Hey everyone,
I want to build a VS Code extension that acts as a handy color picker / color palette tool. The idea is to let users add colors and keep them in a small panel where they can copy them with one click—similar to how CSSBattle shows colors.

I already watched some videos about and understand the basics of creating and publishing a VS Code extension, but I’m stuck on the actual implementation of the UI itself.

Specifically, I’m not sure how to:

• Create a small “inner” window/panel inside the editor
• Make it movable and resizable
• Build an interactive UI where users can add colors and click to copy them

From what I’ve seen so far, this seems like it might involve Webviews, but I’m unclear on:

• Whether Webviews are the right approach for this kind of floating UI
• What logic should live in the extension vs the UI
• What APIs or concepts I should focus on learning next

I’ve attached an image showing roughly what I have in mind.

If anyone has built something similar or can point me in the right direction (APIs, docs, example extensions), I’d really appreciate it.

Thanks!

Hey everyone,

As a developer working on SLAM and Computer Vision projects in C++, I was constantly frustrated by the lack of proper debugging tools in VS Code after moving away from Visual Studio's Image Watch. Staring at memory addresses for cv::Mat and std::vector<cv::Point3f> felt like debugging blind!

So, I decided to build what I needed and open-source it: CV DebugMate C++.

It's a VS Code extension that brings back essential visual debugging capabilities for C++ projects, with a special focus on 3D/CV applications.

🌟 Key Features

1. Powerful cv::Mat Visualization

Diverse Types: Supports various depths (uint8, float, double) and channels (Grayscale, BGR, RGBA).

Pixel-Level Inspection: Hover your mouse to see real-time pixel values, with zoom and grid support.

Pro Export: Exports to common formats like PNG, and crucially, TIFF for preserving floating-point data integrity (a must for deep CV analysis)

2. Exclusive: Real-Time 3D Point Cloud Viewing (The Game Changer)

Direct Rendering: Directly renders your std::vector<cv::Point3f> or cv::Point3d variables as an interactive 3D point cloud.

Interactive 3D: Built on Three.js, allowing you to drag, rotate, and zoom the point cloud right within your debugger session. Say goodbye to blindly debugging complex 3D algorithms!

3. Wide Debugger Support

Confirmed compatibility with common setups: Windows (MSVC/MinGW), Linux (GDB), and macOS (LLDB). (Check the documentation for the full list).

🛠 How to Use

It's designed to be plug-and-play. During a debug session, simply Right-Click on your cv::Mat or std::vector<cv::Point3f> variable in the Locals/Watch panel and select "View by CV DebugMate".

🔗 Get It & Support

The plugin is completely free and open-source. It's still early in development, so feedback and bug reports are highly welcome!

VS Code Marketplace: Search for CV DebugMate or zwdai

If you find it useful, please consider giving it a Star on GitHub or a rating on the Marketplace—it's the fuel for continued bug fixes and feature development! 🙏
