"""Simple MCP server discovery placeholder.

This module provides a placeholder implementation for MCP server discovery
functionality. In a full implementation, this would handle automatic discovery
of available MCP servers from various sources like registries, local installations,
and configured directories.

The discovery system would support:
    - Registry-based server discovery
    - Local server scanning
    - Configuration file parsing
    - Capability-based filtering
    - Version compatibility checking

Classes:
    MCPServerDiscovery: Main discovery class (placeholder)

Functions:
    get_discovery_report: Get a report of discovered servers
    create_mcp_config: Create MCP configuration from discoveries

Note:
    This is a placeholder implementation. The full implementation would
    integrate with the MCPDocumentationLoader and server registries.

    Attributes:
        discovered_servers: Dictionary mapping server names to their metadata.
            Would contain server configurations, capabilities, and locations.
