Hey @getsolaris, thank you for your contribution! This LGTM and I'm happy to merge. Could you please drop a screenshot from the MCP client showing that this tool works as intended?

@jedrazb
Thank you for the quick review!

I've attached three screenshots demonstrating the get_shards tool functionality:

1. Claude Desktop MCP Tool interface showing the tool integration
2. Complete cluster shard status overview using get_shards()
3. Specific index shard distribution using get_shards({ index: "my-index" })

The screenshots verify that the tool:

• Successfully integrates with the MCP client
• Properly displays cluster-wide shard distribution
• Correctly filters and shows shard information for specific indices
• Maintains consistent response formatting for both use cases

Let me know if you need any additional information or clarification!
