Connecting to VSCode

To use this MCP server with VSCode and GitHub Copilot, you have several configuration options depending on your needs.

Prerequisites:

• VSCode 1.102 or later
• GitHub Copilot extension installed and configured
• MCP support enabled in your organization (if applicable)

Workspace Configuration (Recommended for Projects)

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"
      ]
    }
  }
}

User Configuration (Global Settings)

For system-wide access across all workspaces:

1. Open Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
2. Run MCP: Open User Configuration
3. Add the server configuration:

Option 1: Using PyPI Installation

{
  "servers": {
    "markdown-editor": {
      "type": "stdio",
      "command": "python",
      "args": [
        "-m",
        "quantalogic_markdown_mcp.mcp_server"
      ]
    }
  }
}

Option 2: Using uvx

{
  "servers": {
    "markdown-editor": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "--from",
        "quantalogic-markdown-mcp",
        "python",
        "-m",
        "quantalogic_markdown_mcp.mcp_server"
      ]
    }
  }
}

Option 3: Development Installation

{
  "servers": {
    "markdown-editor": {
      "type": "stdio",
      "command": "uv",
      "args": [
        "--directory",
        "/ABSOLUTE/PATH/TO/quantalogic-markdown-edit-mcp",
        "run",
        "python",
        "-m",
        "quantalogic_markdown_mcp.mcp_server"
      ]
    }
  }
}

Development Container Support

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"
            ]
          }
        }
      }
    }
  }
}
