Configuration

MCP Commander automatically manages its configuration in platform-specific user directories:

• Windows: %APPDATA%/mcpCommander/config.json
• macOS: ~/Library/Application Support/mcpCommander/config.json
• Linux: ~/.config/mcpCommander/config.json

When you first run any command, mcpCommander will automatically:

1. Create the user config directory
2. Migrate any existing config.json from the repository
3. Create a default config if none exists

The configuration defines which editors are supported and where their configuration files are located:

{
  "editors": {
    "claude-code": {
      "config_path": "~/.claude.json",
      "jsonpath": "mcpServers"
    },
    "claude-desktop": {
      "config_path": "~/Library/Application Support/Claude/claude_desktop_config.json",
      "jsonpath": "mcpServers"
    },
    "cursor": {
      "config_path": "~/.cursor/mcp.json",
      "jsonpath": "mcpServers"
    }
  }
}

Adding New Editors

To add support for a new editor, simply add an entry to the editors object in config.json:

{
  "editors": {
    "new-editor": {
      "config_path": "/path/to/editor/config.json",
      "jsonpath": "mcpServers"
    }
  }
}

The jsonpath field supports simple dot notation for nested JSON paths (e.g., "config.mcpServers").

Examples

Managing your JIRA MCP server

# Add JIRA server to all editors
mcp add jira-mcp "~/Projects/me/jira-mcp/server.py"

# List all configured servers
mcp list

# Remove from just Cursor
mcp remove jira-mcp cursor

# Check what's configured
mcp status

Adding a server with complex configuration

mcp add filesystem '{"command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", "~/Documents"]}'
