Environment Variables

• GITHUB_TOKEN - GitHub personal access token (required for private Gists and API uploads when GitHub CLI is not available)

Configuration Paths

Cursor

• Windows: C:\\Users\\<username>\\.cursor\\mcp.json
• macOS: ~/Library/Application Support/Cursor/User/mcp.json

Claude Desktop

• Windows: C:\\Users\\<username>\\AppData\\Roaming\\Claude\\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

GitHub Integration

GitHub CLI (Recommended)

If you have GitHub CLI installed and authenticated, the tool will automatically use it for Gist operations. This provides the best experience and doesn't require additional tokens.

GitHub API

If GitHub CLI is not available, you can use the GitHub API directly by setting the GITHUB_TOKEN environment variable:

export GITHUB_TOKEN=ghp_your_personal_access_token_here

Get a token from: https://github.com/settings/tokens

Required scopes: gist

Examples

Example 1: Complete Workflow

# Check current configuration location
portable-mcp path --type cursor

# Replace with a configuration from Gist
portable-mcp replace --type cursor --gist abc123def456

# Upload your modified configuration back
portable-mcp store --type cursor --private

Example 2: Working with Multi-file Gists

# Download specific file from multi-file Gist
portable-mcp replace --type cursor --gist abc123def456/cursor-config.json

Example 3: Custom Paths

# Use custom source and destination
portable-mcp replace --json-url https://example.com/config.json --destination ./my-config.json

Example 4: Merge Configurations

# Merge remote config with local (useful for partial updates)
portable-mcp merge --type cursor --gist abc123def456

Multi-file Gist Support

When working with gists that contain multiple files, you can specify the exact file using the format:

portable-mcp replace --type cursor --gist gist_id/filename.json

Example:

# Download specific file from multi-file gist
portable-mcp replace --type claude --gist 50007c6cd60db13cf8477b3b5caa96f0/claude.json

Filename Handling

The tool automatically preserves original filenames when uploading:

• claude_desktop_config.json stays claude_desktop_config.json
• mcp.json stays mcp.json

This makes it easier to identify and organize your configurations in gists.
