To use this MCP server with VSCode and GitHub Copilot, you have several configuration options depending on your needs.
Prerequisites:
Create a .vscode/mcp.json file in your workspace root to share the configuration with your team:
Option 1: Development Installation (Recommended)
For this project, use the development setup since you're working with the source code:
{
"servers": {
"markdown-editor": {
"type": "stdio",
"command": "uv",
"args": [
"--directory",
"${workspaceFolder}",
"run",
"python",
"-c",
"import sys; sys.path.insert(0, 'src'); from quantalogic_markdown_mcp.mcp_server import mcp; mcp.run()"
],
"cwd": "${workspaceFolder}"
}
}
}
Option 2: Alternative Development Approach
Using environment variables for Python path:
{
"servers": {
"markdown-editor": {
"type": "stdio",
"command": "uv",
"args": [
"--directory",
"${workspaceFolder}",
"run",
"--",
"python",
"-m",
"quantalogic_markdown_mcp.mcp_server"
],
"cwd": "${workspaceFolder}",
"env": {
"PYTHONPATH": "${workspaceFolder}/src"
}
}
}
}
Option 3: Using PyPI Installation (If Installed Globally)
Only use this if you have installed the package globally:
{
"servers": {
"markdown-editor": {
"type": "stdio",
"command": "python3",
"args": [
"-m",
"quantalogic_markdown_mcp.mcp_server"
]
}
}
}
For Windows (adjust command names):
{
"servers": {
"markdown-editor": {
"type": "stdio",
"command": "python.exe",
"args": [
"-m",
"quantalogic_markdown_mcp.mcp_server"
]
}
}
}
For system-wide access across all workspaces:

]
}
}
}
Option 3: Development Installation
{
"servers": {
"markdown-editor": {
"type": "stdio",
"command": "uv",
"args": [
"--directory",
"/ABSOLUTE/PATH/TO/quantalogic-markdown-edit-mcp",
"run",

]
}
}
}
For containerized development environments, add to your devcontainer.json:
{
"image": "mcr.microsoft.com/devcontainers/python:latest",
"customizations": {
"vscode": {
"mcp": {
"servers": {
"markdown-editor": {
"type": "stdio",
"command": "uv",
"args": [
"--directory",
"${containerWorkspaceFolder}",
"run",
"python",
"-m",
"quantalogic_markdown_mcp.mcp_server"

}
}
}
}
}
}
Command Line Installation:
code --add-mcp '{"name":"markdown-editor","command":"uv","args":["--directory","/ABSOLUTE/PATH/TO/quantalogic-markdown-edit-mcp","run","python","-m","quantalogic_markdown_mcp.mcp_server"]}'

Steps
Troubleshooting
✓ Do
✗ Don't
💡 Pro Tips
Architecture
Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.
Protocols
Compatibility
✓ Use when
Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.
✗ Avoid when
Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.
