Configuration Examples

# MCP Gateway server configuration
servers:
  - id: "javadocs-dev"
    name: "Javadocs.dev MCP Server"
    description: "Java documentation and API reference tools"
    transport:
      type: "https"
      endpoint: "https://www.javadocs.dev/mcp"
      auth:
        type: "none"  # Open access
    settings:
      timeout: 30
      retry_attempts: 2
      cache_responses: true
      cache_ttl: 7200  # 2 hours cache for documentation
      rate_limit_handling: true

# Enhanced configuration with caching
servers:
  - id: "javadocs-cached"
    name: "Javadocs.dev MCP Server (Cached)"
    transport:
      type: "https"
      endpoint: "https://www.javadocs.dev/mcp"
    settings:
      timeout: 30
      cache_responses: true
      cache_ttl: 86400  # 24 hours for stable documentation
      cache_size_mb: 100
      headers:
        "User-Agent": "MCP-Gateway/0.8.0 (Documentation-Client)"

Navigation Updates

Create docs/docs/using/servers/javadocs/.pages with:
