Implementation Reference

• src/mcp_server_aws/server.py:208-211 (handler)

  The core handler logic for the 'dynamodb_describe_ttl' tool. It retrieves the DynamoDB client and calls describe_time_to_live with the provided table_name argument.

  elif name == "dynamodb_describe_ttl":
      response = dynamodb_client.describe_time_to_live(
          TableName=arguments["table_name"]
      )

• src/mcp_server_aws/tools.py:386-399 (schema)

  Defines the tool's metadata, description, and input schema for validation, specifying that 'table_name' is required.

  Tool(
      name="dynamodb_describe_ttl",
      description="Get the TTL settings for a table",
      inputSchema={
          "type": "object",
          "properties": {
              "table_name": {
                  "type": "string",
                  "description": "Name of the DynamoDB table"
              }
          },
          "required": ["table_name"]
      }
  ),

• src/mcp_server_aws/server.py:136-140 (registration)

  The MCP server handler that lists all available tools, including 'dynamodb_describe_ttl' via get_aws_tools().

  async def list_tools() -> list[Tool]:
      """List available AWS tools"""
      logger.debug("Handling list_tools request")
      return get_aws_tools()

• src/mcp_server_aws/tools.py:450-454 (registration)

  Combines S3 and DynamoDB tools, including the 'dynamodb_describe_ttl' tool from get_dynamodb_tools().

  def get_aws_tools() -> list[Tool]:
      return [
          *get_s3_tools(),
          *get_dynamodb_tools()
      ]
