MCP Server Configuration

Claude Code Setup

Configure the YouTube MCP server with Claude Code:

# Basic configuration (local scope - default)
claude mcp add youtube-api --env YOUTUBE_API_KEY=your_api_key_here \
  -- uv --directory /path/to/youtube-api-project run python server.py

# User scope - available across all your projects
claude mcp add youtube-api --scope user \
  --env YOUTUBE_API_KEY=your_api_key_here \
  -- uv --directory /path/to/youtube-api-project run python server.py

# With additional environment variables
claude mcp add youtube-api --scope user \
  --env YOUTUBE_API_KEY=your_api_key_here \
  --env YOUTUBE_CACHE_TTL=7200 \
  --env YOUTUBE_LOG_LEVEL=DEBUG \
  -- uv --directory /path/to/youtube-api-project run python server.py

# For team sharing (creates .mcp.json file)
claude mcp add youtube-api --scope project \
  --env YOUTUBE_API_KEY=your_api_key_here \
  -- uv --directory /path/to/youtube-api-project run python server.py

Scope Options:

• --scope local (default): Only you, current project only
• --scope user: Available to you across all projects (recommended)
• --scope project: Shared with team via .mcp.json file

Manage your server:

claude mcp list              # List all configured servers
claude mcp get youtube-api    # Check server details
claude mcp remove youtube-api # Remove server

Within Claude Code:

/mcp                         # Check server status
@youtube-api:                # Reference MCP resources (if supported)
