chat-mode-creator

This MCP server provides tooling to create and manage VS Code chat modes and their associated prompts. It exposes a set of integrated tools that work together to transform developer workflows into ready-to-use chat experiences inside the VS Code Chat UI. Key capabilities include creating chat modes (create_chat_mode) tailored to specific development tasks, getting intelligent mode suggestions (suggest_chat_mode) from user queries, and generating or listing custom prompts (create_custom_prompt, list_mode_prompts) that augment a mode with targeted guidance. The server is designed to align with the official VS Code chat mode and prompt specifications, and it organizes files into a predictable structure under chatmodes and prompts for easy maintenance.

Prerequisites:

• Python 3.8+ installed on your system
• A Python virtual environment tool available (venv)
• Access to install dependencies from requirements.txt

Installation steps:

1. Create and activate a virtual environment

   • Windows (PowerShell): python -m venv .venv ..venv\Scripts\Activate.ps1
   • Linux/macOS: python3 -m venv .venv source .venv/bin/activate

2. Install dependencies pip install -r requirements.txt

3. Run the MCP server locally to verify: python mcp_chatmode_server.py

4. (Optional) Configure your editor integration (VS Code) by adding the MCP server configuration to your settings.json as shown in the documentation, ensuring the paths match your environment.

Tips and common considerations:

• Ensure your virtual environment paths are correctly set in the MCP configuration when integrating with VS Code.
• If the server fails to connect, verify that MCP discovery is enabled in your editor settings (e.g., chat.mcp.discovery.enabled: true).
• Use the provided tool commands to explore available modes and prompts: create_chat_mode, suggest_chat_mode, create_custom_prompt, and list_mode_prompts.
• The file structure follows VS Code standards, with chatmodes and prompts directories under a project workspace. Keep prompts updated as modes evolve.
• If you encounter import errors, check PYTHONPATH and VIRTUAL_ENV in your MCP config and ensure dependencies are installed in the active virtual environment.
