        Args:
            index: Name of the index
        

Implementation Reference

• src/tools/index.py:36-44 (handler)

  The MCP tool handler function for 'delete_index'. It is decorated with @mcp.tool() and delegates the deletion to the underlying search client.

  @mcp.tool()
  def delete_index(index: str) -> Dict:
      """
      Delete an index.
      
      Args:
          index: Name of the index
      """
      return self.search_client.delete_index(index=index)

• src/clients/common/index.py:18-20 (helper)

  The underlying client method implementation that performs the actual index deletion using the Elasticsearch/OpenSearch client.

  def delete_index(self, index: str) -> Dict:
      """Delete an index."""
      return self.client.indices.delete(index=index)

• src/server.py:41-53 (registration)

  Registration of IndexTools (containing delete_index) via ToolsRegister.register_all_tools during server initialization.

  register = ToolsRegister(self.logger, self.search_client, self.mcp)
  
  # Define all tool classes to register
  tool_classes = [
      IndexTools,
      DocumentTools,
      ClusterTools,
      AliasTools,
      DataStreamTools,
      GeneralTools,
  ]        
  # Register all tools
  register.register_all_tools(tool_classes)

• src/risk_config.py:10-14 (helper)

  Configuration marking 'delete_index' as a high-risk operation for IndexTools, which can conditionally disable its registration.

  HIGH_RISK_OPERATIONS = {
      "IndexTools": {
          "create_index",
          "delete_index",
      },
