💻 Commands

🔍 Discovery and Status

# Discover all MCP configurations on your system
mcp discover

# Check status of all editor configurations
mcp status

# List available editors
mcp editors

📝 Server Management

# List all configured servers
mcp list

# List servers for a specific editor
mcp list claude-code

# Add server to specific editor
mcp add myserver "npx @modelcontextprotocol/server-filesystem /tmp" claude-code

# Add server to all configured editors
mcp add myserver "npx @modelcontextprotocol/server-filesystem /tmp"

🌍 Environment Variable Support

# Copy environment variables from current environment
export MCP_LOG_LEVEL=info
export GIT_SIGN_COMMITS=false
mcp add git-server "npx @cyanheads/git-mcp-server" --from-env=MCP_LOG_LEVEL,GIT_SIGN_COMMITS

# Set explicit environment variables
mcp add api-server "npx my-api-server" --env=DEBUG:true --env=API_KEY:secret123

# Combine both approaches
mcp add hybrid-server "npx server" --from-env=LOG_LEVEL --env=CUSTOM_VAR:custom_value

# Use with JSON configuration (merges environment variables)
mcp add json-server '{"command": "npx", "args": ["server"], "env": {"EXISTING": "value"}}' --env=NEW_VAR:added

# Global verbose mode via environment variable
export MCP_COMMANDER_VERBOSE=1
mcp list  # Will run in verbose mode automatically

Generated Configuration

When using environment variables, MCP Commander generates server configurations like this:

{
  "mcpServers": {
    "git-mcp-server": {
      "command": "npx",
      "args": ["@cyanheads/git-mcp-server"],
      "env": {
        "MCP_LOG_LEVEL": "info",
        "GIT_SIGN_COMMITS": "false"
      }
    }
  }
}

🌍 NEW: Add to All Discovered Configurations

# Automatically discover and install to ALL MCP configurations
mcp add-all myserver "npx @modelcontextprotocol/server-filesystem /tmp"

# Works with JSON configurations too
mcp add-all myserver '{"command": "npx", "args": ["-y", "@modelcontextprotocol/server-memory"]}'

🗑️ Server Removal

# Remove server from all configured editors
mcp remove myserver

# Remove server from specific editor
mcp remove myserver cursor

ℹ️ Help and Version

# Show help
mcp --help
mcp help  # Same as above

# Show version
mcp version

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"]}'
