Summary

Fixes #27978

Add audio content support to MCP tools by implementing _process_audio_content method and updating content type handling in MCPTool class.

Changes

  • Added AudioContent import from core.mcp.types
  • Implemented _process_audio_content method to handle audio content processing
  • Added logging configuration for better debugging

The implementation follows the same pattern as existing image content processing, decoding base64 audio data and creating blob messages with appropriate MIME type metadata.
