Implementation Reference

• src/tools/alias.py:14-22 (handler)

  The handler function for the MCP tool named 'get_alias'. It is decorated with @mcp.tool() and delegates the call to the search client's get_alias method, which performs the actual API call.

  @mcp.tool()
  def get_alias(index: str) -> Dict:
      """
      Get alias information for a specific index.
  
      Args:
          index: Name of the index
      """
      return self.search_client.get_alias(index=index)

• src/clients/common/alias.py:10-12 (helper)

  Helper method in AliasClient that implements the core logic of retrieving aliases using the underlying Elasticsearch/OpenSearch client's indices.get_alias API.

  def get_alias(self, index: str) -> Dict:
      """Get aliases for the specified index."""
      return self.client.indices.get_alias(index=index)

• src/server.py:44-53 (registration)

  Top-level registration where AliasTools (containing the get_alias tool) is included in the tool_classes list and registered via ToolsRegister.register_all_tools.

  tool_classes = [
      IndexTools,
      DocumentTools,
      ClusterTools,
      AliasTools,
      DataStreamTools,
      GeneralTools,
  ]        
  # Register all tools
  register.register_all_tools(tool_classes)

• src/tools/alias.py:16-21 (schema)

  Docstring providing input schema description (index: str) and purpose; used by FastMCP for tool schema generation along with type hints.
